A little branch of it drains an old sulfur mine at the end of McDonnell Avenue–our own acid mine drainage! I think the rocks there are the same stuff that’s in the old Leona Quarry, mapped as quartz keratophyre. Very hard, yellowish-gold colored rock that appears all over the city in stone walls and crushed stone. But I haven’t walked up the streambed yet.

There are so many places to visit. Today I walked up Broadway and onward all the way to Skyline, then down Broadway Terrace–a mammoth walk with about 1400 feet elevation gain.
