Death Valley National Park, California




With the recent heat wave in the west and Death Valley setting an all-time June world record temperature of 129.9 degrees F, only 4 shy of its all-time world record, I thought it would be a good time to reflect upon our two visits to Death Valley National Park.



Death Valley National Park is a fascinating place or geologic formations and to study how life struggles to survive in such an inhospitable place. Located in the rainshadow of the Sierra Nevada and California coast ranges, Death Valley would already be a very dry place. But, include the fact it is within the high pressure zone of the North American deserts and at such a low elevation, and this makes it the hottest and driest place in North America. But, just because it is so hot and dry, doesn't mean nothing can survive there.


And in both of our visits there, once in December and once in March, we found out that it isn't always dry. In fact, on both occasions, we were hit with major rainstorms that dropped nearly an inch of rain and made up abandon our camping plans. Thus, if we concluded based on our experiences alone, Death Valley is a very wet place indeed.


Nonetheless, the heat and aridity, have prevented vegetation from covering the land and have exposed the soils and bedrock below to the erosional effects of the occasional torrential rain. This has exposed some spectacular geologic features, including the Artist's Palette, where minerals of different types, expose rocks of different colors including the greens and blues of copper, reds of iron, purple of manganese, and various others.

Of course, one of the most famous spots is Badwater Basin, where salty/alkaline springs emerge at the lowest spot in North America at 282 feet below sea level. While it was called Badwater due to the inability of people or livestock to drink the water, amazingly it does support an ecosystem of specialized aquatic insects and the endemic Badwater snail.

Another interesting location just north of Badwater Basin is the Devil's Golf Course. This large expanse consists of huge chunks of of salt-covered mud. The Devil's Golf Course is the dry lake bed of the ancient Lake Manly that occupied the entire valley to a depth of 30 feet during the Ice Age.

While the mud layer is some 1000 feet deep, due to it being slightly higher than Badwater Basin, it remains above the water table and is usually dry. But, the wind-resistant salt crystals have allowed the flat lake bed materials to be eroded into sharp and chunky shapes.

Golden Canyon
Next on the trip is the Golden Canyon. This easy one mile loop hike through the canyon is extremely beautiful. The golden and yellow hues contrast with the reddish rocks on the cliffs above. In addition, within the rocks, you can see white layers of halite.

Another interesting canyon to explore is Mosaic Canyon, just past Stovepipe Wells. Mosaic Canyon is called that because it is filled with dense conglomerate breccia rocks embedded with large and colorful stones. This route is up to 2 miles long before it ends at a dry waterfall.

Mosaic Canyon
Be aware, like we were, that if a big winter storm is rolling in, Mosaic canyon is prone to flash flooding. We escaped just before the rain began to dump and we had to give up our camping plans and head to Las Vegas. It is during such rare storms, that strong winds push the rocks across the thinly wettened mud of the Racetrack. No one has actually seen the rocks move, especially since being on the mud during a rainstorm would cause you to get stuck. But, during its normally dry conditions, it is an interesting sight.

One place we didn't get to go on either trip was 11,000 foot Telescope Peak. This large mountain rises high above the floor of Death Valley and indicates the shear scale of the Basin-and-Range extension that drops valley floors and raises mountain ranges. In both occasions it was covered by snow and impending storms made hiking it impossible. But, it even maintains a forest of limber pine and mountain mahogany on its slopes. Sometime we'll get up there to see the panoramic view.

One last place of interest at Death Valley National Park is not actually in the main part of the park. It is Devil's Hole, home to the endangered Devil's Hole pupfish. Devil's Hole is actually located in the Ash Meadows National Wildlife Refuge, but the pool itself is part of Death Valley National Park. The Devil's Hole pupfish has the smallest range of any vertebrate in the world. The hole is only about 15 ft x 5 feet. While the hole itself drops for some 1000 feet, the pupfish can only live in the top 2-3 feet of it where the algae they feed on grows.

Devil's Hole
The pupfish found this site during the Ice Age when much of the region was covered in pluvial lakes and connecting streams, like Lake Manly in Death Valley. When the climate warmed and dried, the populations of pupfish became isolated from each other and this one found this refugia. They are adapted to the contant 92 degree thermal waters and alkaline pH of the limestone caverns. While their population has normally ranged from 150-500 individuals, following the "tsunami" of March 2012 (caused by an earthquake in Mexico) and several flood events, the population was measured to be just 35 in April 2013. The population may go extinct. We'll have to wait and see...

Hiking the La Plata Range, Colorado


When visitors arrive at Mesa Verde and climb the big slope up onto the mesa from the visitor center, they are often awed by the view of the the mountains just across the Mancos Valley. This southwestern-most segment of the Rocky Mountains is the La Plata Range. This small range is often overlooked by hikers by the larger San Juan Mountains to the east and north. But, with elevations up to over 13,000 feet on Hesperus Mountain, it is definitely work to side trip to get some real alpine experience.

The La Plata Range is the closest area of the Rocky Mountains geographically to Flagstaff, and we had a desire to get a little "alpine" experience in before the summer monsoons and their associated lightning storms really got underway. There are a number of trails in the La Plata Range and the 500-mile long Colorado Trail crosses the range. In addition, it's highest peak, Hesperus Mountain at 13,237 ft is the "Navajo's Sacred Mountain of the North"

As you drive east from Cortez to Durango on US-160, there will be a turnoff to the La Plata Range just after passing the Hesperus Ski Area. The road starts off paved as it passes a number of summer homes and ranchettes, then is good dirt as it enters the La Plata Canyon, passing a number of camping areas and additional summer cabins. But, once it leaves the camping zone, it become a rough rocky road with a high clearance vehicle recommended.

Looking down La Plata Canyon

Most people will brave the road up to the intersection of the Colorado Trail, where they can hike 1.4-mile up to Taylor Lake, located  at about 11,400 feet. From the edge of the lake, you can admire beautiful wildflowers and the entire Cumberland Basin that makes up this portion of the range. But, standing some 600 feet above you is the headwall to the ridgetop where the real views are.

The trail is pretty easy going up the slope above Taylor Lake. The only sketchy part is the final 50 feet on a steep and slippery rocky face. But, upon reaching the top you instantly get a view of Hesperus Mountain and back across the Cumberland Basin. But, since the saddle is not at the ridgetop and there are dense willows blocking the view in other directions, you will need to follow the trail to the right through the brush to the highest point a few hundred feet further.

Approaching Taylor Lake, in the basin above

There, you will be able to look out across the Mancos Valley to Mesa Verde National Park, and north toward the Lizard Head Peaks and into the San Juans in the distance. In June, the wildflowers are spectacular.

The trail you are on is the Colorado Trail and it heads 500 miles from Durango to Denver, weaving through the La Plata Range, San Juan Mountains, and other alpine environments. Keep on it until it drops into a little saddle between two higher ridges to get the most panoramic views. This is where I turned around, but you can continue on the ridgetop for a couple more miles before it drops back down into the montane forest of Engelmann spruce and subalpine firs.


Be aware that Colorado has the monsoons in summer which result in regular afternoon thunderstorms. Do not go above treeline if it appears as though lightning will occur. We did our hike in mid-June realizing it was a bit before the monsoons would really get going and knowing it was a light snowpack this year so most of the snow was melted off. In another year, this hike would not yet have been possible in June. If you do go in the summer when thunderstorms are brewing, get a really early start.

I've heard that hikers who do the 14'ers have to start their hikes at 4:30am to reach the summit just after sunrise so they can get down before noon when the thunderstorms get going. But, we knew the humidity was low and storm development was unlikely this day. Thus, all we saw by mid-afternoon were a few poofy clouds passing by.

So, if you live in Arizona and want to get to the closest set of Rocky Mountain alpine, then the La Plata Range may be the place to go.
