There aren’t too many geologic oddities in the National Capital region, so London Bridge seemed worth a look. It’s a natural limestone arch created by Burra Creek, which flows underneath, and is probably most interesting for its very regular shape. This is particularly evident given the chaos around it. It’s surrounded by rough, muddy ground full of wombat burrows making it nearly impossible to get close. I should have just waded in for a look… given how wet I was about to get in the gathering storm.
