The poorly written caption on this unused Mike Roberts card C23925 says, in its entirety, “The Sentinels, along the General’s Highway, is typical of the largest and oldest trees to be found in the park.”  Leaving aside ambiguity about singular and plural, there is one “The Sentinel” near the park’s museum, and then there are “sentinels,” a type of tree more numerous in the area.  In any event, the card is OK.  Grade: 1
