Well, it was a great idea, but the timing was wrong, courtesy of the Aspen wildfire in the Sierra National Forest.
Case in point: Here's what the view from Minaret Vista is supposed to look like:
Here's what it looks like now:
The Mammoth Lakes air quality monitoring station showed the following PM-10 graphs (concentration of particles less than 10 microns) for the duration of my stay in the area:
Things looked to be improving (slightly) on July 31, but the spike just after midnight on August 1 was the deal-breaker. Acclimation was impossible...not just because of the high concentration of particulates (although that was bad enough), but because of the atmospheric carbon monoxide (CO) content. CO's ability to bond to hemoglobin is between 200 to 300 times that of molecular oxygen, so it gloms onto the hemoglobin cells and saturates them...meaning, they can't bind oxygen. You can breathe as hard and as fast as you want, but you'll develop an oxygen debt just sitting around in camp. Light hiking is inadvisable; strenuous hiking is impossible. Camping at 9,000 feet felt like hoofing it at 14,000 feet.
The air quality folks finally issued a "Stage 1 Health Advisory" on Thursday, August 1, but by that time I already knew it was hopeless. The fire was only about 35% contained at that point, and the decision had already been made to let it burn up to the treeline. The terrain is brutally steep, and all they can do to get containment is try to cut firebreaks very far away from the fireline, where they have some kind of access, and let the fire burn up to them. That means the fire is going to be burning for many days to come.
To top it off, the winds were mostly out of the southwest, which drove the smoke smack dab toward Mammoth, where I was camped. I checked with the rangers at the Red Meadows Road entry station on Wednesday at about 5:00 p.m., and they said they were advising everyone to stay east of Minaret Summit Road — in other words, not to go exactly where I wanted to go. And they were advising people with respiratory issues (I'm mildly asthmatic) to get the hell outa Dodge. They expected the winds to kick up to around 30 mph on Wednesday night, bringing lots of new smoke into the area. That's exactly what happened.
Anyhow, after three mostly sleepless nights of hacking in a couple of Mammoth Lakes campgrounds (Lake Mary and Twin Lakes), waiting out the fire, I threw in the towel on Thursday, and headed for home. As of today, the fire is 50% contained, but even after they get full containment, they're just going to have to let a huge area burn itself out. It will be weeks before the area is habitable for anything but indoor living.
Feh. Great idea, bad timing. So it goes. The best laid plans of mice and men...etc. :whatthehell:
