The area that now makes up the Marble Mountain Wilderness has been protected in one form or another since 1931. It gained its current statues in 1964 when the US Congress passed the Wilderness Act. The name "Marble Mountain" is due to the unique makeup of the light colored limestone run through with lines of black metamorphic rock, which gives some of the peaks a distinct marbled look.

Getting to the Caribou Lakes means climbing thousands of feet to a basin below Caribou Peak. Once you arrive you'll be treated to three good sized lakes and a number of small ponds, all surrounded by granite peaks. There is a campsite along the shore of Upper Caribou Lake as well, so you can make this an overnight journey if you wish.
