From my man Brian W:

The ice flow on babcock blvd is in great shape. 30-40 feet high. Steep but not vertical.

From downtown pittsburgh: route 28 north a couple of miles, take the millvale exit and turn right onto evergreen rd. follow that road as it winds its way thru millvale and go straight thru 3 stoplights. you will go a couple of miles (evergreen rd becomes babcock blvd) and the diamond wire spring company will be on your left. park on the right directly across the street. it is a single line with small variations.

if the stream isn't thick enough to cross, there is a small bridge a hundred feet back down the road...
