Tourmaline, when I said "I don't remember seeing it here before", I was referring to the picture, not the Richfield Building. Thanks for the reminder of
previous posts.

There have been several mentions of Chutes Park on NLA, and
Los Angeles Past posted a couple of great pictures in
post #739, but I don't recall seeing a colorized picture before. The postmark dates it at 1905.

The neighboring Washington Park has also had a few passing mentions, but I didn't find any pictures. The Chutes Theater and waterslide are clearly visible in the background of the second picture below.

The parks were located just south of Washington Boulevard between Grand and Main. The site was just marked as "The Chutes" on the 1910 Baist map.

The "Base Ball Grounds" are shown by 1914.

The stands of the ballpark are much larger by 1921, and the site next to the ballpark is now labeled "McCartney's Washington Gardens".

Today, nothing remains of either park. Olive, Hill and Broadway have all been extended through the site.

And finally, a recent aerial shot.
