Thumb is plainly marked on the map available from the Forest Service office in Lander, from which we embarked. We drove to the trailhead outside of town and hiked for a few hours along a well-marked trail. When we got to within a mile of Thumb, Mathiesen and I pitched our tent and, for the next couple of days, fished the surrounding streams. The weather started out bad and got even worse, with a snowstorm driven by gale-force winds being the main event. We never caught any goldens above the timberline, but the plump cutthroats and brook trout in the lakes, potholes and streams took out some of the sting. They also sufficed for breakfast, lunch and dinner.
