Horseshoe Lake, California

Richard Wong recently blogged about his trip up to Horseshoe Lake in the Eastern Sierra. He noticed the many dead trees close to the parking lot. (To get a better picture, here is a Bing Map of Horseshoe Lake.) And he wondered why there were no warning signs.

When we visited Horseshoe Lake back in 2003, they used to have big warning signs up there, right next to the parking lot at the end of the road. These look like warning signs, and at that time the signs made very clear that you better watch your step (click the image to enlarge):

For example, this sign reads:



The soil concentration of CO2 in the entire hazard area is 20 to 90%, compared to a normal level of less than 1%. CO2 is heavier than air, and can collect in depressions on a calm day.

ON THE BEACH, please adhere to the following guidelines for your safety:
* Don’t dig in the ground (a source of CO2).
* No sitting, picnicking or sunbathing on the beach.
* Keep children and pets out of the area.

Symptoms include dizziness, shortness of breath, rapid pulse and heartbeat, etc. – Loss of consciousness and death can occur very quickly.

For more information, see the interpretive signs on the buildings or contact the Ranger Station at 760-934-5500

The phone number belongs to the Mammoth Lakes Visitor Center & Ranger Station. Unfortunately, there is no further information on their web site (or I just did not find it). Which puzzles me a bit, because it does make sense to promote this area as it is a really interesting sight, and obviously additional warnings might help preventing accidents and injuries.

Having said that, the whole area is just one super beautiful spot. Even more so, when the weather is really good (hehe)! When traveling to the Eastern Sierra, you simply have to go up there. Here are a few more photos of our trip. And our USA Photo Gallery covers our entire four week trip to California, Arizona, Utah, and Nevada.
