Mt Yale and the ridge to Mt Harvard, via Henninger Flats

Mt Yale (4760+') is really just a bump on the ridge to Mt Harvard (5441'), but it is on the Lower Peaks list, and is a fun little summit to visit.

Mt Harvard is on private property and is used for broadcasting. A heavily signed "No Trespassing" road goes directly to the summit, but we will approach from the south to avoid trespassing.

After parking, we will cross Eaton Canyon and use a steep equestrian trail to access Mt Wilson Toll Road. There's a convenient way to access a ridge which directly ascends to the water tank on the peak NW of Henninger Flats. We continue from there nearly 3 miles to the cross-country route to Yale. It begins where the Hastings Ridge joins the Mt Wilson Toll Road.

A short push through chamise will take us to a generally good trail along a ridge.

After tagging Mt Yale, we will continue up the ridge almost all the way to Harvard. Just before the antennae, there's a private property boundary where we will stop...

Stats: 13 miles, 4750' gain on fire roads and steep ridge-line use-trails.
