We got up early Monday and took a shuttle to the Bear Lake Trailhead. We chose to climb Flattop mountain. It was a challenging, but not overly taxing climb from a base of about 9,300 feet to the summit at about 12,300 feet. The views (as seen in pictures 6-12) were nothing short of spectacular. Unfortunately, this altitude provided to be pretty burdensome to Steve, and he spent the afternoon fighting bouts of altitude sickness in our tent. Adding to the strain was our first encounter with Rocky Mountain thunderstorms which start at almost exactly 2:00 pm every summer day. We were camping in a treeless valley and the frequency of lightning strikes was pretty intense. No problems resulted and the storms subsided quickly.
