Orbital View: Dam That Is Big

As Scott Kelly makes his way across China in 10 installments (he did Australia in 17), I stumbled upon this view in China while looking for new Instagram accounts to feed the daily feature:

The caption from Daily Overview:

Water from the Jinsha River surges through the Xiluodu Dam near Xiluodu, China. Arch dams like this one are designed so that the force of the contained water presses against the arch, compressing and strengthening the structure by pushing it into its foundation. At 937 feet (286 meters), the dam in Xiluodu is the fourth tallest in the world and is primarily used for hydroelectric power generation.

Looks like a trilobite to me.
