Bob Schneider, one of Tuleyome's co-founders and current member of Tuleyome's Advisory Council, and Bill Grabert, a Tuleyome staff member turned volunteer Tuleyome Board Member, co-authored the following Tuleyome Tale. Although it was written in 2020, the safety measures outlined are timeless and a good reminder given the current temperatures in the Berryessa Snow Mountain National Monument region.


This area gets HOT in the summer. Every year, in extreme heat of summer, there are rescues of hikers in our region. Heat and dehydration can be life threatening, but rescues, which put our emergency personnel at risk and keep emergency resources occupied, can be avoided with just a little planning and common sense. Hiking in the midst of summer is possible...here are some recommendations on how to hike safely.


Check the weather. Don’t hike on high temperature days. Take LOTS of water. Know your route. Be prepared to turn around when temps increase and water runs low.


Get out early. If you can be on the trail at sunrise, all the better. Take lots of water because you will be sweating it out. Perspiration is essential to keeping your body temperature regulated. In this area, very few of the trails have water nearby. Some no-water trails, like the difficult 14.5-mile Berryessa Peak trail, should simply not be attempted on a hot summer day unless you plan to carry a couple of gallons of water with you. Getting out on the trail extra early has the added benefit of avoiding most other people who start on the trail at 9:00 AM or so. On the hottest days, plan to be finished with your hike and off the trail by 11:00 AM.


There are two main ways to keep cool while you’re out on a hike: shade and evaporation. You can get shade from a tree, but you can also get it from a hat. Wear a hat! A lot of the trails around here are lacking in trees, but you will always have shade if you wear a nice broad hat. You don’t see it here very often, but an umbrella can also be helpful. The best evaporative cooling is natural perspiration and a little breeze. However, a nice trick on an extra hot day is to carry a mister spray bottle for extra cooling from time to time.


One way to learn about hiking and the hikes in our region is to first go with others. Tuleyome, the Sierra Club, and many “Meet Up” groups may offer hikes. Check them out. You will learn to enjoy the outdoors safely and you will meet fellow hikers.


Sometimes accidents do happen. We are truly fortunate to have dedicated public safety men and women who take time away from their families and incur personal risks to aid those in need. But let’s be sure that we take personal responsibility to avoid unnecessary rescues and do our best to let them enjoy their time at home. 


Top Twelve Safety Pointers:


Know where you are going – and let others know. There are maps online and trail books at outdoor stores. Plan your trip and let your family and friends know your plan. New hikers can first take trips with hiking groups in the region.

A whistle? Signal mirror? Cell Phone? It’s nice to be able to call for help when really necessary but keep in mind that often trails can be well out of cell phone range. Before you make that “rescue me” call, ask yourself: Is somebody injured? Is this a life-threatening emergency? Do I really need help or can I figure this out for myself? 

Take a hat, dark glasses and sunscreen with you – and use them.

It is good to have some basic First Aid supplies. Super glue and duct tape are invaluable but you can also purchase small First Aid kits at outdoor stores.

Keep up your energy level. A sandwich, nuts, dried fruit and energy bars can give a quick boost and make for a happier hiking experience.

Be aware of the nature dangers in our area. The two most common dangers around here are poison oak and ticks. The best way to keep away from both of them is to stay on the trail. If you’re not brushing up against vegetation, you should be fine. However, it’s always wise to shower with plenty of soap and check your skin for ticks after a hike.

Rattlesnakes: watch where you put your hands and feet. They don’t always rattle. If you see a snake, just avoid it. It will be trying to avoid you too. Most likely, it’s a harmless gopher snake not a rattlesnake.

Mountain lions and bears: yes, they do live around here. Attacks are extremely rare but it’s wise to be particularly aware at dawn or dusk to keep your dog and children close to you.

Take a flashlight. Starting your hike late and getting “be-nighted” is not a reason for rescue! Flashlights or headlamps can allow you to hike during those unplanned nights out.

Take lots of water; at least two quarts for a day hike. Also, drink it! Your goal should be to end the hike with an empty (or nearly empty) water bottle.

Weather can change dramatically on the trail so be prepared for everything. Thunder storms are rare here, although they can happen. Fire is a real danger. If a strong summer wind kicks in, you might want to think about heading home, and if you smell smoke, get out fast.

If you hike with your dog, be aware that dogs can overheat even if you’re offering them water. Dogs cannot sweat the way humans do. They can cool themselves somewhat by panting with their tongues out, but that can only go so far, especially without shade and rest. I will always remember passing a very sad couple on the exposed ridge overlooking Cold Canyon carrying their unconscious 70 lb. dog in the 100+ degree heat. 

Stay on the trails. Trails are built through careful planning and with the landscape in mind. Cutting switchbacks causes erosion and habitat destruction… and ultimately someone has to do the work to repair the damage caused by inconsiderate hikers. 

Google “ten essentials” for serious outdoor preparation, with one caveat for our area. Ten essentials lists always contain supplies for making a fire. Please do NOT make a fire in the inner coast mountains in the late summer and fall. It takes very little for these mountains to go up in flames.

Everyone can enjoy our region and to do so safely. Our first responders want to help when really needed but let’s avoid all unnecessary call-outs. When hiking, have fun, be smart and keep safe! And, as always, don’t litter; pack out what you take in.

If you’re a friend of Tuleyome you likely know a bit about our (it belongs to all of us) newly expanded favorite National Monument - the Berryessa Snow Mountain National Monument. You may also recognize that federal public lands are lands that are owned and/or managed by the United States federal government for the enjoyment of its citizens. And, you probably know that in addition to national monuments there are also national parks, national forests and national historic places but did you know that there are many more public land designations as well?! There are many (MANY!) different types of federal public lands. Most of them are held for conservation, resource management and public recreation. The United States Department of the Interior (DOI) oversees several federal agencies that manage various public land designations and the United States Department of Agriculture (USDA) oversees other agencies that steward public lands. Federal public lands in the United States, District of Columbia and US territories total approximately 640 million acres and occupy nearly 30% of the land area. The National Park Service is an agency within the DOI and oversees not only national parks but also most national monuments and other natural, historical and recreational properties with various title designations or units. These include national preserves, national lakeshores and seashores, national rivers and wild and scenic rivers and national scenic and historic trails, among others. Today The National Park Service currently manages 433 combined parks/units including 63 national parks, 87 national monuments, 75 national historic sites, 64 national historic sites and many other designations totaling 85 million acres in all 50 states, the District of Columbia and US territories. Their management focus is preserving the ecological and historical integrity of these special places for public use and enjoyment. The Bureau of Land Management (BLM) is a federal agency also under the direction of the DOI. The BLM’s mission is “to sustain the health, diversity and productivity of public lands for the use and enjoyment of present and future generations.” We here at Tuleyome think that’s pretty dang good and we often partner with them on varying components of public land use and enjoyment. The BLM is responsible for the management of a substantial portion of the nation’s public lands including some of our most historic and scenic landscapes and natural resources for all to enjoy. The United States Fish and Wildlife Service (USFWS) is another agency operated under the DOI and is the oldest conservation agency in the United States. It was established in 1871 to help monitor the country’s game fish populations. Today the USFWS manages our nation’s wildlife refuges to conserve the habitat, plants and wildlife found there. The national wildlife refuge system began with Pelican Island in 1903 and today there are over 560 refuges across the country. It’s been said that if “national parks are America’s best idea, national wildlife refuges are America’s best-kept secret”. Although, they don’t seem like a very stealthy secret since they receive over 50 million visitors a year! The United States Forest Service (USFS) was established in 1905 and is an agency under the USDA. It is the United States’ predominant forestry agency leading the world in sustainable forest and grassland use, management and stewardship, research and conservation. Today they are responsible for the management of 154 national forests and surrounding areas that total nearly 200 million acres in 43 states, the Virgin Islands and Puerto Rico. The agency also provides stewardship assistance to tribal, state and local governments, private landowners and corporations to improve conditions on about 900 million acres of forests in the U.S. Fun fact - Yellowstone was the United States’ first national park established in 1872. But, at the time Wyoming was still a U.S. territory so Yellowstone was managed by the federal government using the Army and the African American Buffalo Soldiers. Fun fact - the designation National Monument has been given to many different sites ranging from natural reserves, historic military scenes, prehistoric ruins, fossil sites AND to the Statue of Liberty. Fun fact - there is at least one national wildlife refuge in every US state and territory. Fun fact - The Forest Service obviously manages forests but did you know that they also manage grasslands? Did you know… that the Berryessa Snow Mountain National Monument is jointly managed by both the BLM and the USFS, not the National Park Service!? Whether you’re exploring places where you won’t find a motorized vehicle or places where you might not find a parking spot, you can bet there is at least one type of federal public land just a hop, skip and a jump from you! The numerous designations within the National Park System sometimes confuse visitors. The names are created in the Congressional legislation authorizing the sites or by the president, who proclaims "national monuments" under the Antiquities Act of 1906. Many names are descriptive—lakeshores, seashores, battlefields—but others cannot be neatly categorized because of the diversity of resources within them. In 1970, Congress elaborated on the 1916 National Park Service Organic Act, saying all units of the system have equal legal standing in a national system. National Park These are generally large natural places having a wide variety of attributes, at times including significant historic assets. Hunting, mining and consumptive activities are not authorized. National Monument The Antiquities Act of 1906 authorized the President to declare by public proclamation landmarks, structures, and other objects of historic or scientific interest situated on lands owned or controlled by the government to be national monuments. National Preserve National preserves are areas having characteristics associated with national parks, but in which Congress has permitted continued public hunting, trapping, oil/gas exploration and extraction. Many existing national preserves, without sport hunting, would qualify for national park designation. National Historic Site Usually, a national historic site contains a single historical feature that was directly associated with its subject. Derived from the Historic Sites Act of 1935, a number of historic sites were established by secretaries of the Interior, but most have been authorized by acts of Congress. National Historical Park This designation generally applies to historic parks that extend beyond single properties or buildings. National Memorial A national memorial is commemorative of a historic person or episode; it need not occupy a site historically connected with its subject. National Battlefield This general title includes national battlefield, national battlefield park, national battlefield site, and national military park. In 1958, an NPS committee recommended national battlefield as the single title for all such park lands. National Cemetery There are presently 14 national cemeteries in the National Park System, all of which are administered in conjunction with an associated unit and are not accounted for separately. National Recreation Area Twelve NRAs in the system are centered on large reservoirs and emphasize water-based recreation. Five other NRAs are located near major population centers. Such urban parks combine scarce open spaces with the preservation of significant historic resources and important natural areas in location that can provide outdoor recreation for large numbers of people. National Seashore Ten national seashores have been established on the Atlantic, Gulf and Pacific coasts; some are developed and some relatively primitive. Hunting is allowed at many of these sites. National Lakeshore National lakeshores, all on the Great Lakes, closely parallel the seashores in character and use. National River There are several variations to this category: national river and recreation area, national scenic river, wild river, etc. The first was authorized in 1964 and others were established following passage of the Wild and Scenic Rivers Act of 1968. National Parkway The title parkway refers to a roadway and the parkland paralleling the roadway. All were intended for scenic motoring along a protected corridor and often connect cultural sites. National Trail National scenic trails and national historic trails are the titles given to these linear parklands (over 3,600 miles) authorized under the National Trails System Act of 1968. Affiliated Areas In an Act of August 18, 1970, the National Park System was defined in law as, "any area of land and water now or hereafter administered by the Secretary of the Interior through the National Park Service for park, monument, historic, parkway, recreational or other purposes." The Affiliated Areas comprise a variety of locations in the United States and Canada that preserve significant properties outside the National Park System. Some of these have been recognized by Acts of Congress, others have been designated national historic sites by the Secretary of the Interior under authority of the Historic Sites Act of 1935. All draw on technical or financial aid from the National Park Service. Other Designations Some units of the National Park System bear unique titles or combinations of titles, like the White House and Prince William Forest Park . Types of federal public lands National Parks : Managed by the National Park Service (NPS), these lands are preserved for their natural and cultural resources for future generations to enjoy. National Forests and Grasslands : Managed by the U.S. Forest Service (USFS), these areas are used for multiple purposes, including timber, recreation, and wildlife management. National Wildlife Refuges : Managed by the U.S. Fish and Wildlife Service (USFWS), these lands are primarily for the conservation of fish, wildlife, and plants, but many also allow compatible wildlife-dependent recreation like hunting and fishing. National Conservation Lands : These are public lands designated for their conservation value and are managed by the Bureau of Land Management (BLM). The BLM manages more public land acreage than any other agency. Management and use Management: Federal lands are managed by various agencies, with the U.S. Forest Service (Department of Agriculture) and the Bureau of Land Management, the National Park Service, and the U.S. Fish and Wildlife Service (all under the Department of the Interior) being the primary ones. Resource Extraction: Some federal lands are available for resource extraction like oil, gas, and mining, which can be a source of controversy and debate over conservation versus extraction. Recreation: The lands offer a wide range of recreational opportunities, such as hiking, camping, wildlife viewing, hunting, and fishing. Information: You can find information about specific public lands, including maps and regulations, on the official websites of the managing agencies.
