Secret Canyon near Lost Lake- Cajon Pass...

I was poking around near Lake, and I happened  across this rock formation, that is surrounded by the grasses and other plants that are fed with underground water.  This was about a 1/2 mile north of the actual lake.

I call it a "secret canyon", because this area doesn't appear to be visible from the nearby 15 Freeway.  It's like a hidden world- "Lost Lake" is aptly named.
