Whale Rock Trail
Yes, it looks like a beached whale. Whales don't typically survive in this desert landscape.
Whale Rock is a rounded, eroded sandstone fin that is fun to climb. Handrails are provided to help people reach the top, where you are rewarded with impressive views out over Upheaval Dome. Many people enjoy free climbing the rock, bypassing the handrails.
The trailhead is located near the end of the Upheaval Dome Road, in the Island in the Sky District of Canyonlands National Park. From the trailhead you can see the rock, which does somewhat resemble a beached whale.

Viewpoint on Rock(38.4283, -109.917)
The rock is rounded, but it is easy to walk along the top. The best views are found about half-way along the rock, but you can continue along the top to the western edge.
When you are ready to return, just retrace your steps back to the trailhead.
