Gooseberries and Currants
(the only genus in the Grossulariaceae family)
This genus has two basic forms, gooseberries and currents, and then a few outliers. There are several species of currants which all look basically like chaparral currant, and several gooseberries which look like hillside gooseberry.
The fuchsia-flowered gooseberry is an exception and is looks like nothing else.
Three species may be seen on the West Fork of Cold Spring. As far as I can tell, all the Ribes plants below the turnoff to Tangerine falls are Bitter Gooseberries, while those between that turn-off and the Cold Spring Tunnel are all Fuchsia-flowered, and those on the burnt over slopes above the tunnel are currants.
