Bob Schneider and Bill Grabert looking at Lake Berryessa and Snow Mountain in the distance while hiking at Stebbins Cold Canyon

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.

Policy Corner: Protect our Wildest Areas

August 7, 2026
Our wildest areas are under threat. In June, the Administration moved to weaken protections for our wildest public lands - those designated as wilderness, Wilderness Study Areas, Lands with Wilderness Characteristics, and recommended Wilderness. What do these areas represent? Millions of acres of untrammeled backcountry. The Department of the Interior, US Forest Service and National Park Service initiated the first step in unraveling these protections. They’ve called for a “review” of eight policies, opening the door to weaken protections and paving the way for short-term extractive industries, commercial development, and resource fragmentation at the expense of long-term conservation management of some of our wildest remaining public lands. Nearly 200 million acres of wildlands across the west could be impacted by this review, including approximately 120 million acres of Wilderness Study Areas and wilderness quality lands, and 75 million acres of designated wilderness areas. This includes the nearly 94,000 acres in Cache Creek, Cedar Roughs and Snow Mountain Wilderness areas in Berryessa Snow Mountain Nation Monument right here in our own region. These policies guide how federal agencies identify, manage, and steward designated Wilderness Areas, Wilderness Study Areas, and lands with wilderness characteristics. Together, they influence the management of millions of acres of federal public lands and translate statutory requirements into day-to-day management decisions. Continuing to protect wilderness qualities is consistent with protecting recreation. In many cases, wilderness-quality land provides the best opportunities for backcountry recreation; a CA outdoor industry responsible for 545,448 direct jobs valued at $38.1 billion. The total value-added worth of CA outdoor recreation is $81.5 billion, 2.2% of our gross domestic product. The Department of the Interior’s actions present a false choice between stewarding wilderness lands and providing opportunities for recreation. Let’s tell the Administration that we oppose these rollbacks and are committed to protecting our wild places. Sign on to the Wi lderness Review- National Sign-on Letter opposing five different actions across the three agencies by August 12th. Together, we can show this administration that we care about protecting these special places today and into the future. Sandra Schubert Executive Director

Donor Spotlight - Sarah Davis

August 7, 2026
I first heard about Tuleyome when I retired early from UC Davis eight years ago. I was looking for local organizations for volunteer opportunities. I discovered Tuleyome and got connected with Bill Grabert and Nate Lillge. I helped them lead hikes and school programs, then took the CA Naturalist course through Tuleyome. My capstone project was to lead a backpacking trip into the Cache Creek wilderness, which I did just as COVID was descending on us. I was, and still am, impressed at how such a small local non-profit has both ensured preservation of important wild areas and invested heavily in outreach to local schools. Working with kids from Lake County in the Redbud area was eye-opening and extremely gratifying. Some of them had literally never been on a hike in spite of growing up so close to all that spectacular wild land! I donate to Tuleyome to help them keep up the great work!!! I’ve spent countless days hiking in and enjoying the Cache Creek area; what a gem of a local resource! And, only last spring was I able to get up to Snow Mountain…so glad it’s preserved and accessible for camping and hiking. Wow! A wilderness area near my home - that’s amazing. I’m incredibly grateful for Tuleyome’s hard work that resulted in preservation of these important wild places, and I look forward to seeing what’s next.

Monumental Questions - What Makes California Newts Special?

By Kristie Ehrhardt • August 7, 2026
Driving around the Berryessa Snow Mountain National Monument one rainy day revealed a network of dirt roads that were slick as snnn… well, you probably know. The wet weather made driving less than optimal for the Subaru we were in but for our amphibian friends, the low-riding California newt, the warm, misty conditions were sublime. California Newts ( Taricha torosa ) are endemic to California, which means that they are extra special because they are only found here. They occur below 6,000 feet along the Coast Ranges from Mendocino County south to San Diego County. They are also found in the foothills and western slopes of the Sierra Nevada in the San Joaquin Valley with a few isolated populations in southern San Diego County. They utilize both wetland habitat including natural and artificial pools and ponds, reservoirs, creeks and streams for breeding during winter and spring, and upland areas such as chaparral and woodland habitats where they spend summer and fall. California Newts have stubby little toes attached to short, stocky legs. Adults range from about two and three quarters inches to about three and a half inches long, not including the tail. Their bellies and undersides of their neck and chin are bright golden yellow to orange with a reddish-brown to slate gray back. California Newts reproduce from late fall to early summer depending on rainfall amounts and habitat conditions. Adults migrate from their upland refugia to their preferred wetland to breed. Eggs are attached to submerged vegetation or under rocks and females can lay up to six masses of nearly 50 eggs a day. The eggs hatch in two to six weeks depending on water conditions and temperature. Larvae are aquatic and have gills and fins. After several months the larvae begin to exit the pond and set about metamorphosing into adults and do not return to the pond again until they are ready to breed. Larvae eat small aquatic invertebrates and organic matter; adults eat insects, slugs, snails and worms as well as other amphibian eggs and larvae. Adult California Newts are highly toxic. Like other members of the genus Taricha , adults have glands on their skin that secrete the potent neurotoxin tetrodotoxin - the same toxin that is found in harlequin frogs and pufferfish. Side note, this makes them poisonous rather than venomous (like rattlesnakes). Tetrodotoxin is hundreds of times more toxic than cyanide and potent enough to kill most vertebrates. The toxin affects sodium channels and makes it so neurons are unable to fire which results in lethal muscle paralysis. One of the only predators of adult California Newts are garter snakes. Garter snakes are one of the very few organisms that have evolved to develop a resistance to the tetrodotoxin produced by the newts. Garter snakes can ingest the toxic newts with limited effects which has created an evolutionary arms race (coevolution). As the garter snakes develop stronger immunity to the toxins only the most poisonous news survive which in turn results in future generations of news with even stronger toxins. This leads to a population of garter snakes that have developed a resistance to the stronger toxin levels and and on it goes. Loads of them were bumbling along the edges of the wet dirt road that rainy day. We made several stops to relocate those that were attempting to cross but seemed to stall out in the middle, always placing them facing the direction they were aimed. I don’t know if they were heading out to their natal ponds to mingle and breed, or on their way back to nap in their upland refugia but they were definitely enjoying the day. The California Newt is currently a California Species of Special Concern due to habitat loss and invasive non-native species introduction which makes seeing so many of these little stumpy legged tetrapods enjoying the Monument even even more groovy!
