For the first time ever in the backcountry I get a stomach bug. I don't have diarrhea or vomiting, it just feels like someone is punching me in the guts. So I pretty much stop eating. The hike to Isabel is just under 10 miles from the lower Park Creek camp. It's not all that difficult, the the last 1,000 feet to the lake are hot because the Rampage Fire of 2003 scorched the place. But the stomach bug saps my strength. A big old thunderstorm rolls in right after I set up my tent. I take a long nap. My tent is wonderfully waterproof. That evening the sun goes down low and red. To the right is Vigil Peak. The mountain in the distance is Grizzly. The mosquitoes are as thick as soup.
