Long Description:
A paved walkway south of Highway 14 makes for a great wildflower stroll in the spring. The path winds through a couple of depressions likely formed the the Missoula Ice Age Floods plucking basalt out of weaker parts of the underlying basalt flows.

A longer hike north of Hwy 14 along Catherine Creek leads to an area where an immense basalt wall has separated from the bedrock behind, and a window has developed in the wall through weathering and collapse of the less competent portions of the wall.

A difficult and treacherous climb through the window leads to the gap behind, where a granitic boulder (an erratic) is wedged in the crevasse on the north end of the gap. It is likely a granitic rock from Canada that was caught up in the Ice Age Cordilleran Glacier and was lodged in one of the ice dams blocking the Clark Fork River/Glacial Lake Missoula. When the ice dam broke it was floated here by one of the floods in a block of ice.
