Sleeping Giant - Helena, Montana Landmark

Beartooth Mountain, aka The Sleeping Giant

Geology, from:  

 As you look north from town, you will notice the Sleeping Giant (Beartooth Mountain) keeping his ever-vigilant watch over the valley. Actually, the entire head of the Giant is similar to the purple-brown shonkinite plug of the Adel volcanics that outcrop further to the northeast. The prominent chest at 6,800 feet is composed of Precambrian Belt Ravalli formation rocks (quartzite, argillite, and shale) and Pritchard formation rocks (banded slate with interbedded sandstone). Much of the hard black slate used as building and landscaping rock around downtown Helena is from Towhead Gulch that forms the gap between the legs and feet of the Giant.


A distant cousin of Billy the Mountain, The Sleeping Giant is going to have a bit of a shock when he finally wakes up and looks in the mirror. He is probably going to have to call out some contractors and have a little work done on that nose.
