Anna Sklar is an underground historian of the most unique variety -- the author of a history of the Los Angeles sewer system, the first book to approach a city's history in this manner. Sklar is also interested in aboveground matters of earth, as she demonstrates in these two photographs, below, sent to Chicken Corner.
According to the author:
In November 1937, a passenger train apparently caused a massive landslide in Elysian Park above Riverside Drive. Thought you'd like to see two photos; one more amusing than the other which seems to have been taken as the earth was moving.
I don't recognize the street here in the photograph immediately below, but I assume it is Riverside. The building on the left has a small sign that reads "Hotel." It looks like a new building at the time of the photo, but I am not sure if it hasn't been razed by now.
This one could be Riverside near Figueroa, if it isn't the narrows where the 110 dissects Elysian Park.
