(Clamshell Truck trail)

Take I-210 to the Myrtle Avenue off-ramp.
Go north on Myrtle Avenue for 1.6 miles to Hillcrest Boulevard. Turn right.
Go 0.2 mile to Canyon Boulevard. Turn left.
Go 0.4 mile to Ridgeside Drive. Turn left.
Go 0.4 mile to a narrow unmarked paved road on the left, just north of 865 Ridgeside Drive. This is the Clamshell Truck Trail. Park on the street at this point.

From the beginning of the Clamshell Truck Trail (1130'), go up the road a short distance to a locked gate at the beginning of a dirt road. Pass this gate and continue up the dirt road about a mile to a shallow saddle with a firebreak coming down a ridge on the right.
Turn right and go up this firebreak to where it turns into a cat track.
Keep right here and follow the cat track as it goes off to the right of the ridge and then regains the ridge.
Continue up the ridge to the top of Clamshell Peak. There is usually a register on this summit.
Go off the east side of the peak, descending about 250' to the Clamshell Truck Trail at about 4100'.
Go east on the road about 1 1/4 miles to where a ridge comes down from Rankin Peak on the right.
Go up this ridge to Rankin Peak. There is a monument to Rev. Rankin for whom the peak is named on the top of this peak.
Continue east down through a saddle, over a bump, into another saddle, and then up to the summit.
