Below are a few photo postcard images by Lindley Eddy.   

For 30 years, Mr. Eddy was the photography concessionaire at Giant Forest (Sequoia National Park).    During some of these years, he apparently spent the winter months in the Three Rivers/Lemon Cove area.  
In 1934,  Lindley Eddy married the widowed  Helen Gladys (Emery) Aoki.

 The photographer's stamp on the back of this postcard states:  "Photograph by Lindley Eddy,  Kaweah, Tulare Co., Cal.".    

It's postmarked 7/20/1911.   Camp Sierra was along the northern margin of Round Meadow.

 Close up:

 Image circa 1912.

Image of the Giant Forest Hotel/Lodge dining hall, circa 1916.  This lodge was at the same location as Camp Sierra.

 The Giant Forest Lodge in snow, circa 1916.

Road to the General Sherman Tree, circa 1920.

 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.

Close-up:

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.
