Here are a couple of places we visited with this TB, but there were no caches nearby.
Big Mountain is just north of Kalispell, Montana. In the winter, it's a big ski resort. In the summer, you can ride the chairlift to the top and hike or mountain bike.
Avalanche Lake is in Glacier Park. It was about a 2 mile hike to the lake. We counted 5 different waterfalls coming into the lake!
