Lym lake was discovered by my father while herding sheep for his grandfather. He was searching for a missing lamb. At the time he discovered it he lived on the family ranch near Evanston, WY. I believe he was about 14 years old at the time. Says John Lym
Blacks Fork - West Fork has a delightful 3.5-mile-long class I-III whitewater stretch nearby, the Bridge to confluence with East Fork section. This stretch of Blacks Fork - West Fork is advised
for whitewater boaters of medium knowledge. You should check current conditions ahead of going; whitewater boating can get risky. Scow Lake is a nearby lake that you could go to, and don't leave Lym Lake without first going for a hike along the Highline Trail.
