HossC, the ravine's dimensions look about the same as the 1960 photograph (except for the trees obviously).
I'd say the city decided
against a dump at this site that was so close to a public school.
Here's another image I stumbled across at LAPL while searching for the municipal dump. Andy Gump's Dump.(that's him on the sign)

I thought it wouldn't hurt to see it again.
-obviously the owner named his cafe after the highly successful comic strip...created in 1917.

After 50 animated shorts (1920-21) distributed by Paramount, Andy Gump and his family starred in two-reel comedies (1923 to 1928)
produced by Universal Pictures.
Here's actors Fay Tincher (as Min), Joe Murphy (as Andy Gump) and Jackie Morgan (as Chester).

Fay Tincher somewhat resembles Mary Astor in this photograph.
