Come join us for a natural history exploration and hike through neighborhood streets and the (potentially muddy) Glen Canyon. We’ll start at the headwaters of Noe Valley then go down rocky, muddy, wooded trails into Glen Park. We’ll look at springs and former springs, creeks disappearing into sewers, creeks flowing freely through Glen Park, old photos and former creek beds. We’ll try to identify remnants of an early grove and we’ll end at Glen Park BART.

Same spot today, top of Glen Canyon (Twin Peaks is up the hill to the left) looking east.

There will be casual, participatory discussion and a few map unrollings during brief presentations from your guide, water mapper Joel Pomerantz. Get to know how the south and southeast slopes of Twin Peaks fit the bigger picture of San Francisco water history and social landscapes.

The total walk length is less than three miles. It will include short difficult sections climbing or descending steeply. We will stop and discuss for a time in various places, so don’t depend on hiking to keep you warm—bring extra layers!
