Jr. High graduation

I'm not sure when he went to live with Gram in LA but for sure he graduated from Le Conte Jr. High in LA.
He never spoke of going to camp but I found pictures of him at Little Green Valley.

At first I thought the woman was Gladys as she looks like Gladys later in life. Eventually I realized that the woman was too old. Looking at other photos identified as Gram it seemed clear that that is who this is.
