Not nearly as classic as it's well known neighbor. A couloir of easy/moderate snow that is similar to the lower portion of Skywalker. After about 1000' of snow negotiate a rockband by passing it on the right and head west towards the summit of South Arapahoe. In good conditions, Streetwalker could be a reasonable descent route from the summit.
Right of Skywalker about 200 yards. Streetwalker is the rightmost finger of snow
If a belay is desired a couple of pickets and a light rock rack should suffice.
