Upper whitecap LakeMy neighbor Alan and I went on a trek to Whitecap Lakes, near the MT/ID border in July 08. We started at the Boulder creek Trailhead, went over Boulder pass into Idaho. We followed that trail for another two miles then cut across and side hilled it to another ridge and setted in for the night. The next day more side hilling and then we dropped down into White cap lake. Even though it was down hill now, it was still tough hiking down to the middle lake. We camp there, plenty of fish in both lakes. The next day we hiked up the South side of Tin Cup Ridge and then droped down into the cirque above Tin Cup Lake, I was excited to get back to a trail. There were some excellent camp site just below the cirque, although we choose to camp down by the lake. From the Lake its about 8 miles down to the trailhead.
There are alternative routes to Whitecap Lakes, It is my understanding that the old trail to Whitecap lake has not been maitained for many years.
