Start parked next to the bathrooms of Old Powderhorn and skin up the wide clearing to the back of the clearing. Exit into the trees to the left and follow the path of least resistance up and slightly right. Stay right of the unnamed blue run. Find a small clearing next to the road and the pullout. Now decide what run to do.
This slope has a north to northwest aspect and there is some avalanche terrain in the vicinity, so know before you go.
