From midway up up the trail to Conrad Kain Hut. The Bugaboo Glacier is split by a nunatak called the Hounds Tooth. As you get higher you'll see the Hounds Tooth is just a lower, east shoulder of Marmolata Mountain. The distinctive snowpatch of the spire of the same name is in the top-right corner, and just below, you can see the pale green roof of the hut.
