In 2017, I visited the Minnesota Zoo in the summer for the first time. I must say, I was very impressed by the outdoor bird show and the farm (no, you didn't read that wrong, even their farm is impressive.) Anyway, while on my way to the outdoor bird show, I noticed a small cabin with a window into it. The zoo map labeled it as the Mussel Cabin. It had a small aquarium filled with endangered native mussels. They were reintroducing to the zoo grounds. There is no mention of the Mussel Cabin on MN Zoo's website. I could not find it mentioned on this site. Was anyone else aware that this exists?
