Walupt Lake’s name is said to come from a legend of the Yakama tribe. Actually, there appears to be more than one legend for the lake and I’m not sure which one is the original.
The Guthooks trail guide says the lake is named for a legendary pack of wild dogs that lived in the lake and attacked anyone who would turn their back to the lake.
Another story says a Yakama hunter spent several days chasing a mighty deer until it led him to the lake. He saw the deer jump in, swim around the lake, then disappear. As the story goes, hunters since then will sometimes see the great deer swimming in the lake.
I didn’t camp at the lake, but a pond nearby. And though I wasn’t attacked by wild dogs and I didn’t see a mighty deer swimming, mighty animals were nearby.
