Wildfires and Smoke at Lake Tahoe (Considerations for Traveling in the Tahoe Backcountry during Summer)

Copyright © 2018 Jared Manninen

Living at Lake Tahoe and being surrounded by the Sierra Nevada Mountains is like living in a dream. There’s plenty of powdery snow in the winter and sunshine in the summer. The finest outdoor recreation is literally outside your front door.

And, despite the massive influx of visitors that come to Lake Tahoe during the summers and winters and each holiday, the place still maintains its small town vibe.

I moved to Lake Tahoe in 2005 and, ever since, have been learning to live in this dream-like environment. I have to keep reminding myself, though, that with all dreams come the occasional nightmare.

And Tahoe, like anywhere else in the world, comes equipped with its own set of nightmares with which to contend. For example, all that snow we love to ski and snowboard on during the winter makes for crushing avalanches and hazardous driving conditions. Then, each summer brings the potential threat of wildfire.

In response to the 2018 California wildfires that ravaged the state and the resultant smoke that settled in the Tahoe Basin for weeks, I felt compelled to share what I’ve learned about wildfires and living the mountain experience.

This article continues after my update about the current status of Lake Tahoe Wildfire & Smoke hazards.

2020 Lake Tahoe Wildfire & Smoke Summary

On August 17, 2020, wildfire smoke from the Loyalton Fire (near Reno, NV) filled the Lake Tahoe Basin. After that, smoke from other regional wildfires blew into the Lake Tahoe Basin causing persistently poor air quality for over a month. Tahoe experienced periodic breaks from the smoke during that time, but they were few and far apart. Light rains fell on September 18th leading to better air quality, but the AQI jumped back up to 130 on September 21st. The air cleared between September 23-28. It elevated again from September 29th – October 7th, and then finally cleared up for the season by October 8th.

October 14, 2020 – the Lake Tahoe Basin Air Quality Index (AQI) according to PurpleAir is less than 20.

Introduction to Wildfire

Throughout the summer, west coast wildfires become front-page news. Obviously, the people who lose their loved ones and homes suffer the greatest losses. However, wildfires impact everyone in the region.

The air quality is adversely affected (leading to indirect health hazards), and the psychological effects can be significant. It’s hard not to feel like the atmosphere itself – the very air we breathe – conspires to oppress us. The ceiling drops and the world becomes smaller.

With each acre that burns, there’s one less acre for people and wildlife to roam freely. That is, at least until the area recovers. And, due to evacuation measures implemented by the affected municipalities, people gravitate toward the main thoroughfares. This transforms those corridors into a consolidated mass of refugees.

Clearly, this isn’t the summer vacation anyone plans.

California technically is a Mediterranean climate. This means that precipitation falls primarily in the winter. The summers, on the other hand, are often void of any rainfall. So, wildfires in California during the summer are a fact of life. And, believe it or not, they’re necessary for many species to continue surviving.

According to the National Park Service, “As many as 90 percent of wildland fires in the US are caused by humans.” The fact that they occur so easily and with such vigor is evidence that they’re a necessary part of the regional ecosystem.

That said, humans are also a species trying to survive on the west coast. But the only thing wildfires provide for them is the destructive potential to wipe out neighborhoods and displace communities.

My First Experience with California Wildfires

My introduction to wildfires was during the devastating Angora Fire of 2007. This fire occurred in Meyers, CA, just west of South Lake Tahoe. The specific origin location of this fire was the now defunct Seneca Pond in Meyers. In less than a week, 250+ homes were destroyed .

At the time, I was living within South Lake Tahoe’s city limits. So, I didn’t lose my home or have to evacuate like so many of my friends.

No one was officially charged for causing the fire. But, an illegal campfire ignited the Angora Fire. The people who built the campfire didn’t adequately extinguish it.

Nearly every summer since the Angora Fire, wildfires have brought to Tahoe a few weeks of smoke filled air.

In the summer of 2018, smoke filled the Lake Tahoe Basin from multiple regional California wildfires:

  • Ferguson Fire (near Yosemite)
  • Carr Fire (near Redding, CA)
  • Mendocino Complex Fire (between Redding and Sacramento)

The photos featured on this page illustrate how the smoke settled in South Lake Tahoe in 2018.

Causes of Wildfires and Tips to Reduce Your Risk of Starting Them

Errant lightning strikes from summer storms are definitely high on the list of ways in which wildfires can ignite. People again, however, are the main problem through actions such as:

  • leaving campfires unattended or improperly putting them out
  • carelessly tossing aside cigarette butts
  • trying to burn their trash instead of simply packing it out

The Voltaire Canyon Fire (just east of Lake Tahoe) in June of 2018 illustrates that last scenario. Two people camping in Voltaire Canyon attempted to “clean up” their campsite by burning their toilet paper and shit.

Needless to say, the fire burned out of their control.

There are numerous other ways in which wildfires can start, and many of them can be random and unpredictable.

For example, the flat tire on a vehicle’s trailer caused the Carr Fire that destroyed over 1,500 structures. Sparks created by the friction between the rim of the flat tire and the asphalt shot into nearby dried vegetation.

Other examples include:

  • glass from a broken bottle magnifying the sun’s rays enough to set dry grasses alight
  • a vehicle’s hot exhaust pipe making contact with dried vegetation and resulting in ignition.

Additional Notes about Wildfires:

Fire can travel along a tree’s root system by smoldering underground for months, and then re-igniting at a later time.

If you think a big snowpack will make everything better for the following summer, think again. The excess snow does help to saturate the land. However, it also enables grasses and opportunistic species to thrive. These species, otherwise, wouldn’t necessarily grow if the soil was drier (i.e. from a normal or lower snowpack level).

Then those species are quick to dry out when the moisture dissipates. And, ultimately they create an even greater fire hazard in the form of abundant ground fuel.

There are so many different ways people can accidentally start wildfires. So it’s up to each individual who travels in the backcountry, sidecountry, and frontcountry) to be mindful of their presence. And, they should do everything possible to minimize their impact by embracing the Leave No Trace seven principles.

Minimize Your Impact in the Backcountry and Reduce Your Fire Risk

I didn’t even like building campfires at the shelters (with fire rings) back in 1999 when I thru-hiked the Appalachian Trail. It was such a waste of time and energy. Then you’re breathing in smoke all night while trying to sleep.

I can’t say this enough, but your best bet to avoid causing a wildfire is to simply avoid building campfires altogether. I’ll hammer that one home a few more times before I’m done with this article…

And there are some other considerations to take into account with regards to minimizing your fire risk.

Don’t Build Campfires in the Backcountry

One of the biggest steps toward minimizing your impact in the backcountry, as well as dramatically decreasing your risk of starting a wildfire is to stop having campfires.

Let me repeat – if you truly love and care for wildlands stop building campfires.

To many this is blasphemous, I know. However, artificially introducing fire into the backcountry is as risky and insane an act as any. Unless you’re standing at death’s door, there are no legitimate reasons to have a campfire in the backcountry.

Resist all peer pressure.

Resist all of your learned habits that camping = campfires.

This way of thinking is outdated and not commensurate with the world in which we currently live.

Don’t build one. Don’t do it. Period.

Again, Don’t Build Campfires in the Backcountry!

But what about all of those beautiful moody and nostalgia-inducing photos I see on Instagram of people sitting by their campfire on a granite ledge, next to an alpine lake, or at the beach?

I agree that those photos look beautiful. But when you stop to think about it for half a second, you’ll realize that the majority of those fires captured in frame were built from scratch. This means that they were either illegal or, at least unethical, campfires.

And, after the photographer leaves the site having gained 1,000 more followers for their IG account and 10,000 more “likes” on their photo, they leave in their wake scorched earth.

Have you ever tried to completely erase the evidence of a fire? Impossible.

So what you leave behind is a blight on Mother Earth for everyone else to enjoy.

Oh, and you’re not doing anyone a favor by leaving that brand new fire ring intact. All you’re going to succeed at is increasing the odds of burning to ash the area you claim to love.

By introducing the idea (i.e. through social media) of building campfires in remote terrain you normalize the behavior so that people no longer view building a campfire as a risky endeavor (which it is, always!). They are then more likely to copy the act, thereby increasing the overall risk for starting a wildfire.

What’s the alternative to building a campfire, then?

Wear warmer clothes and enjoy being a part of nature — not apart from nature.

Campfires…

  • attract moths but repel just about every other critter out there
  • diminish the view of the stars overhead
  • encourage you to stay awake far longer than you would if you were camping without one — then you sleep in late and miss the following morning’s sunrise

Going to sleep and waking up with the sun is one of the primary reasons I love to backpack. This experience evokes a sense of connection with the natural rhythm of the day.

Don’t Smoke in the Backcountry

You’d be surprised at how many long-distance thru-hikers (i.e. Appalachian Trail, Pacific Crest Trail) are also smokers. I’ve never understood it but … whatever.

The bottom line is that if you do smoke in the backcountry, stop moving, stop hiking, stop wandering around, while you’re actually smoking. Hang out and enjoy the scenery for that short while. But then field strip that cigarette butt and dispose of the filter properly (i.e. pack it out).

The problem with walking and smoking is that you run the risk of depositing embers along the way.

Don’t Burn Your Trash in the Backcountry

Hobos from the 1940s called and they want their beliefs back. If you have at least a sixth grade education, you shouldn’t even be humoring the thought of burning your trash.

Burning your trash instead of leaving behind a pile of trash just means you’re leaving behind a pile of burnt trash. Get with the program and pack out all of your trash (and that includes toilet paper).

The easiest way to pack out your trash is to not bring excessive packaging in the first place. Before leaving the house (or store), field strip all of your food stuff. Basically just get rid of all the extra packaging. This minimizes the amount of packaging on-hand. Then, you can just collect everything you plan to dispose of in a Ziploc bag.

On a backpacking trip lasting 3-7 days, I never come close to filling a gallon Ziploc with trash.

Inspect and Properly Maintain Your Vehicle 

Sometimes access to the trailhead requires you to drive on undeveloped roads through the backcountry. This is fun stuff!

However, the experience can turn into a nightmare if your vehicle…

  • overheats
  • has an electrical issue and catches fire
  • breaks due to physical stresses placed on the suspension

Often along backcountry roads you’ll be operating at slower speeds for longer periods of time while negotiating variable terrain. This places excessive stress on your vehicle’s engine. How? By causing it to run at a higher temperature for a sustained period of time.

Make sure the engine oil and coolant are full and look clean. Be mindful or your vehicle, especially if its engine and undercarriage are coated with various fluids. Excessive fluid should compel you to have your vehicle checked out for leaks no matter where you plan to drive. However, it’s especially important to address if you’re going to be driving under backcountry conditions. These leaking fluids can catch fire due to…

  • a hot engine
  • sparks from electrical issues under the hood
  • sparks caused by friction between the metal of your vehicle and rocks

Always carry in your vehicle a fire extinguisher. And, have it readily available when driving along backcountry roads.

Also, everything on/in your vehicle will bounce around more when driving on backcountry roads compared to a paved road. Your suspension system will be under a lot of strain as a result. Objects within the cab of your vehicle might fly around (and hit you or break a window). And delicate parts such as wiring could move and make contact with other parts of the vehicle.

Last Thoughts about Wildfires

Regardless of where you live, determine the local forecast and weather conditions for your planned destination. This way you’ll be more prepared to time your adventure appropriately (i.e. between storms).

If you’re visiting Lake Tahoe, the following short list features websites that provide relevant information about current conditions:

As much as I complain about the smoke, I know it’s only an inconvenience for me. Wildfire smoke, in and of itself, isn’t a life-changing event like actually losing a home or a loved one.

That said, moderate or modify your activities when recreating in an area where smoke has accumulated due to wildfires.

And, governing bodies can implement and enforce laws. Ultimately, however, the individual is the only entity who will prove to be the best (or worst) steward of wildlands.

Like Smokey says, “Only you can prevent forest fires.”
