This is the view looking down what is the East Fork of the San Gabriel River.
Rainwater and snowmelt from here flows roughly 75 miles to Seal Beach at the end of the 605 freeway.

Wow--you were lucky to get in there before they sealed it up--looks really interesting. Hope you post more adventures on this blog--night hiking is a great idea!
