Looks like Burma. She arrived in 1990. And she has always had the little tusk poking out one side of her mouth.
The current elephant house and enclosure opened in early 1992, but this photo does not appear to show a brand new building, so is likely the Old Elephant House, shortly before its decomission as such.
This is the old enclosure. And it is definately Burma because now that I think of it, Kashin and Burma were the only elephants there. This must of been just before November when the new elephant area opened.
Burma aged 10 years. It’s lucky that by only being housed in this exhibit for two years, she was able to avoid the arthritis that afflicted Kashin (1968-2009).
