Rocks and paths in North Berkeley, 4.2 miles, 900 feet elevation

This is a new hike for us; we're hitting many of the landmarks in the Nor Cal Geological Society's 2003 Field trip "Silica Rich Rocks in the Berkeley Hills."
We'll meet at the Marin Circle, then head up paths and roads through Berkeley.
Destinations include:

• Indian Rock
• Mortar Rock Park
• John Hinkel Park
• Grotto Rock Park
• A landslide area and earthquake fault evidence near Spruce Street and Marin Ave.
• Cragmont Park
• Remillard Park
• Cordornices Park (take a trip down the cement slide)
• Berkeley Rose Garden for brief lunch stop

An Alltrails map can be found here. AllTrails list this route as 4.2 miles and 843 feet climbing.
Kids are welcome, but dogs are not.
We'll "pass the hat" for requested $2 contributions at the start of the hike.

Bring fluids and snacks; we'll stop for a short lunch at the Berkeley Rose Garden (which has a great view of the Bay).
We should be done in about three hours, although times are never certain.
Getting there
Parking: We're in neighborhoods here, so most parking is free--but keep your eye out for parking restrictions and red zones. If you want to carpool, leave a comment.
Public Transit: AC Transit Line 7 will get you to the Marin Circle, and Line 18 will get you a few blocks away on Sutter Street. If you're coming on BART, you can get off at Downtown Berkeley station and switch to the Line 7 bus (or ask in the comments section if anyone can pick you up--North Berkeley is best for meeting someone if carpooling).

If it's pouring rain, we'll cancel...check here Friday night for updates.
