Nice route if you have limited time. Probably WI3 to 3+ depending on whether you finish on the right or left side.
Descend by rappelling once down the route from the trees (there is usually a webbing anchor at the top, but it might be wise to bring some extra webbing just in case).
Obvious gully starting within the road cut at the top of Crawford Notch. The gully is on the right hand side of the road as you drive up from the Frankenstein area. Park as for other Mount Willard climbs. The approach takes about 3 minutes from the parking area.
Generally thick ice that takes good screws. You can set an anchor in the trees at the top.
