In a fine little drainage between Notchtop and Flattop mountains, you will find a multitude of rock and snow/ice routes. There are many possible routes up and down Flattop (due south), Notchtop (due north), and the terminus of the drainage, Ptarmigan Cirque (due west).
Park at the Bear Lake Parking lot (newly renovated) at the end of Bear Lake Road. Hike north of Bear Lake on the Flattop Mountain Trail. Follow signs to Odessa Lake, forking off of the Flattop Mountain trail. Break off trail and continue southwest past Lake Helene and up the obvious drainage.
