Photo postcard of the old Giant Forest Hotel (Sequoia National Park).  Post-marked 1916.

I've also seen this place referred to as Hotel Sequoia.

I noticed that both of these cars appear to have their engine cowlings off.  Possibly to prevent overheating  (?).

Back then driving to Giant Forest could be quite the difficult.    The road to the park was unpaved, and at times very rough.  e.g. It basically just followed the old lumber road created by the ill-fated Kaweah Colony in the late 1880's.
