What's living in Utah's inland ocean?

Just west of Salt Lake City, there's a tropical fish habitat and scuba diving school called Bonneville Seabase. What will happen to the thousands of marine animals living in natural saline pools when the owners close shop? Plus, we hear from our partners at KUNC about invasive crayfish in the Upper Colorado River Basin. We also hear an audio postcard from KGNU about the country's largest gem and mineral show, which takes place every year in Denver. //Photo: Christine Finch is responsible for taking care of the fish at Bonneville Seabase.
