Monumental Questions - What is Snow Mountain Wilderness

Kristie Erhardt • August 9, 2024

Have you been there? Maybe you’re planning a trip or maybe you can’t wait to go back. The Snow Mountain Wilderness Area includes over 60,000 acres that straddles Colusa, Glenn and Lake Counties in the Northern Coast Range. It is one of the 806 designated Wilderness Areas established under the Wilderness Act signed into law by President Lyndon B. Johnson in 1964. The Wilderness Act established the Wilderness Preservation System, “...for the permanent good of the whole people” and is considered one of America’s greatest conservation achievements. The law requires that federal land management agencies such as the National Park Service (NPS), the Bureau of Land Management (BLM), the United States Fish and Wildlife Service (USFWS) and the United States Forest Service (USFS) manage the designated wilderness areas to preserve their individual wilderness characteristics. For a natural area to be considered for a Wilderness Area designation, it must meet stringent criteria: that it be large enough for personal solitude, possess exceptional opportunities for rudimentary and unrestrained recreation, be primarily free from human interference, and have distinct qualities that differentiate it from all other lands. Many Wilderness Areas have these qualities as well as other intangible characteristics that help develop and inspire a relationship with nature and adventure.

 

Today, nearly 112 million acres in the United States are designated as Wilderness Areas. These areas range in size from the nine million acre Wrangell-St. Elias Wilderness in the Alaskan tundra that supports grizzly bears, caribou, wolves, Dall sheep and wolverines to the three acre Pelican Island Wilderness in Northern Florida which supports threatened and endangered species such as green sea turtle, Florida manatee and wood stork.

 

The Snow Mountain Wilderness was established in 1984 and totals 60,222 acres. It is within the Mendocino National Forest and is managed by the USFS. The heart of the Snow Mountain Wilderness is Snow Mountain itself. The wide-topped mountain has an East Peak with an elevation of 7,050 feet and drains water toward the Sacramento River to the east, and a West Peak with an elevation of 7,021 feet and drains into the Eel River basin to the west. The mountain also supports the largest waterfall in the Mendocino National Forest. Because of the contrasting elevations within the area, the unique geology of the region, and the montage of ecosystems, Snow Mountain is often considered a biological sky-island.

 

The entire 60,000+ acres of wilderness bears only about 40 miles of trails leaving the remainder of the area extremely remote and untraveled. Hiking the East Peak will give visitors a stunning view of the Sierra Nevada, Clear Lake, the Sacramento Valley and the surrounding Mendocino National Forest.

 

The geology of the Snow Mountain Wilderness (and the entire Berryessa Snow Mountain National Monument) is fascinating. The Snow Mountain region formed during the time of the dinosaurs (Mesozoic era) and is made up mostly of sandstone, shale and chert. As Snow Mountain was being reared, the layers of rocks got pushed, twisted and distorted resulting in the lower elevations surrounding the mountain still being sedimentary rocks while the upper portion of the mountain is primarily made up of greenstone. Serpentine is also present which may be a remnant of the ocean crust as the mountain was pushed upward. The slopes on the north side of the area were covered by glaciers resulting in small meadows which remain today. 

 

The vegetation in the lower elevations of the area include grasslands with a stunning array of wildflowers following years with abundant rainfall, dense chaparral and blue oak woodland. Moving up in elevation, the vegetation community transitions into black oak and mixed conifer forest and higher in elevation you’ll find thick stands of true fir, Jeffrey pine and incense cedar interspersed with rocky outcrops.

 

Because it is so remote, camping is primitive, and there is no reliable source of water during most of the summer. Streams may not be safe for drinking so planning ahead is crucial and be sure to boil or filter all water collected before drinking it. Individual use permits are not required within the Mendocino National Forest however USFS recommends signing in at the trailhead. Because of the rugged terrain and remote location, be sure to check in at the ranger station for the current weather and forest conditions and restrictions prior to venturing out and tell others where you’re heading and when you expect to return. Maximum group size is 25 people or stock animals in the Snow Mountain Wilderness. To maintain wilderness characteristics, only travel by foot or horseback is allowed; no motorized or mechanical equipment is allowed within a wilderness area, wheelchairs are allowed. You are required to obtain a California Campfire permit if your plans include the use of any stove or building a campfire within a wilderness area. Permits are free of change and can be obtained at the USFS or BLM offices or from the California Department of Forestry and Fire Protection.

 

Thanks to the Wilderness Act and the National Wilderness Preservation System, the Snow Mountain Wilderness is part of the nearly 175 million square miles of federal public land that is protected for the solace and enjoyment of current and future generations of humans and wildlife equally.

 

“The purpose of the Wilderness Area is to preserve the wilderness character of the areas to be included in the Wilderness System, not to establish any particular use.”

           -Howard Zahniser (1906-1964) Executive Director of the Wilderness Society and primary author of the Wilderness Act

Welcome Interns!

By Geoff Benn • October 7, 2026
Interns Deana Martinez, Yaquelin Gonzalez, Gabriella Limon, Ben Hubbard, and Keira Lazaro at Woodland Regional Park Preserve. Tuleyome is excited to welcome our largest ever cohort of interns, including four Horticultural Interns and one Communications Intern! Our Horticultural Interns are paired with volunteer mentors at Woodland Regional Park Preserve where they learn about managing invasive plants and monitoring populations of rare native plants. This year’s mentors are Jennifer Hogan and Teri Barry, both longtime volunteers and leadership team members at the Preserve. Our Communications Intern works closely with Program Director Nate Lillge to shape and execute our communications, including social media, e-newsletters, and more. Keep reading to meet each of our interns: Horticultural Intern Yaquelin Gonzalez has lived within the bounds of Sacramento County her whole life, where her mother’s garden and love for rock collecting sparked her appreciation for nature. Her desire to enter the environmental field was further fueled via nature-based field trips during elementary school. After high school, she began studying at American River College and eventually transferred to the University of California, Davis in 2025 to study Environmental Science and Management, focusing on Ecology, Biodiversity, and Conservation. Here, she has gained an interest in soil science as well as plant ecology and hopes to pursue a research career in restoration ecology. In her spare time, she likes to go on nature walks, play the guitar, read, bake, and listen to podcasts. Horticultural Intern Ben Hubbard grew up in Roseville, California where he spent a lot of time outdoors with friends, competing in sports, hiking, as well as instructing elementary school field trips about the environment, specifically wetlands. He just recently transferred from Sierra College to the University of California, Davis and is working towards completing his Bachelor’s degree in Environmental Science and Management with a specialization in Ecology. When he completes his education, he hopes he can make a difference in the world and help to preserve wildlife and natural land for the next generation to enjoy as much as he has. When he’s taking a break from studying you can find him practicing with his recreational sports team, grabbing a coffee, hiking, enjoying a good story, or just hanging out with friends. Horticultural Intern Keira Lazaro is a third year undergraduate at University of California, Davis where she majors in Environmental Toxicology. She’s specializing in pharmacology and biotechnology with hopes to work in a research lab on specific pathogens that attack native California crops. She is also a part of the University Honors Program in Davis and is taking the first couple of steps towards her fourth year signature work on the oxidation chemistry behind electronic cigarette devices, specifically with exposure in indoor environments. Keira grew up in Los Angeles County and hopes to find a career in Southern California once she graduates. When she is able to go back home she spends most of her free time at the beach or hiking. Communications Intern Gabriella Limon grew up in Bishop, California, within the Sierra Nevada and Owens Valley where she became connected with wildlife and stewardship. She spent her later teenage years in Southern California and committed to the University of California, Davis, where she is currently pursuing a Bachelor's Degree in Environmental Policy Analysis and Planning with a focus on conservation management. In addition, she is also a scholar staff member of the UC Davis Women’s Resources and Research Center where she provides STEM-based programming and academic support to students of marginalized identities. Gabby is especially passionate about wildlife justice, land protection, and environmental education. She spends her free time writing, playing video games, tide pooling, hiking, and logging critters. Horticultural Intern Deana Martinez grew up in Arbuckle, California, surrounded by rice fields and almond orchards, which grew her interests in agriculture. She is currently in her 4th year at the University of California, Davis, where she is pursuing a Bachelor’s Degree in Entomology with a Soil Science minor. Along with classes, she is involved in a Nematology research lab, working with plant parasitic nematodes and their interactions with common crop systems in California. She has also held a student position with the Plant Biology research greenhouses as a technician for the past 3 years. Outside of school and work, Deana enjoys hiking, reading, and spending time with her family.

Policy Corner: California Fights Back on Endangered Species Protections

By Shai Demus • October 7, 2026
California’s condors and sea otters are two of conservation’s great comeback stories – species that were once on the brink of extinction and have rebounded thanks in large part to the Endangered Species Act (ESA). That 50-year-old law is now facing one of the most significant rollbacks in its history, and California is fighting back in court. Last week, Attorney General Rob Bonta, joined by a coalition of 21 state attorneys general, filed two lawsuits challenging the Trump administration’s recent changes to the ESA. At the center of the fight is a single but enormously consequential change: the administration rescinded the longstanding definition of “harm” under the Act – a definition that, since the early 1980s, has made it illegal to destroy or damage the places endangered species live, breed, and feed. Without it, habitat destruction itself may no longer count as illegal “harm” to a species, even though most biologists agree habitat loss is the single biggest threat facing endangered species today. The changes don’t stop there. The administration is also making it easier for federal agencies to avoid designating “critical habitat” for at-risk species, and it has eliminated automatic protections for newly-listed threatened species – meaning wildlife officials must now write custom protection rules for each species one at a time. That’s a heavy lift for an agency that has reportedly lost more than a third of its staff, and which currently has 400 species waiting for a protection decision. Why this matters here at home California is home to more threatened and endangered species than any other state. It’s natural to assume the state’s own Endangered Species Act would fill any gap left by federal rollbacks – but legal experts point out that California’s law, as written, doesn’t clearly protect habitat at all. It primarily prohibits killing or injuring individual members of a listed species, not damaging the places they live. That means the very thing under threat federally – habitat protection – may not have a reliable backstop at the state level either. What this means for our work At Tuleyome, so much of what we do, protecting oak woodlands, wildlife corridors, and watershed habitat across our region – depends on the basic principle that a species' home matters as much as the species itself. A condor or a Clear Lake hitch can’t survive court-ordered protection from hunting alone if the habitat it depends on is quietly bulldozed, drilled, or logged out from under it. This lawsuit is about defending that basic principle at the federal level, and it’s a reminder of why local land protection and legislative advocacy matters now more than ever – because the safety net above us may have real holes in it.
