This is the "Bottlecap Gazebo." The leaves are made out of thousands of bottlecaps. There are ladders in the center of it that give you access to the observation deck, but be aware that it's a straight-up climb and getting down was harder than getting up.
Here's what the leaves look like up close.
From up top, you can look across US-95A/50A at the Fernley Train Depot, looking rather forlorn as all of the loaned equipment and exhibits have been hauled away due to the dispute between the Fernley Historical Society and the City of Fernley over actually opening the relocated and restored depot as a museum and visitor center.
What looks like a rock on a stick is, sort of. It's a 9-ton stone slab on a spindle that a single person can set spinning.
This sculpture is called "Desert Tortoise." Note the sign in the foreground being happily ignored.
There are a few more photos in my Flickr account in the same album as those. Just follow the links through the photos if you want to see the others.
Anyone coming up to Burning Man should be able to easily pop in to Fernley proper before turning north to Gerlach, or else look in on your way back, and see what the Burn Hath Wrought here. Mind you, there are still people complaining that the park took out a good place for big-rig trucks to park overnight.
