Halfmoon Campground Professional Guide
Detailed Trail Description from our Guidebook
"The drive into Halfmoon Campground is rocky and slow, but the scenery is what tourists expect to see in Montana—a spectacular mountain range bursting from a valley floor carpeted with ranchland and speckled with cows grazing between the sagebrush. Known as one of the state’s island ranges, the Crazy Mountains rise stunningly out of nowhere and confirm for those driving west on I-90 that yes, indeed, they have finally made it to the Rocky Mountains.
On the western flank is Grasshopper Glacier, a lingering remnant of the glaciers that, like a sculptor’s chisel, carved these mountains by etching away mud and stone. Created some 50 million years earlier, the glacier appeared when magma rose from deep within the earth’s core to the muddy ocean floor and solidified into igneous rock."
