In an earlier post we reviewed how to use Go To Location and other tools to take a look at large holes in the ground. So continuing with that theme we'll take a look at a few more...

Meteor Crater is located in northern Arizona and is over 4000 feet across and 550 feet deep. The impact is estimated to have occurred about 50,000 years ago. The meteor's size was over 150 feet across, creating an enormous impact and heaving 175 million tons of rock out of the earth's surface.

Here we've used Go To Location (Tools > Go To Location) and entered the coordinates of the crater:

And added the topographic map layer from ArcGIS Online so we can compare the aerial and topo of the crater.

Enter these coordinates: 38.513335, -122.104272

in Go To Location and you'll find the Monticello Dam in California. It has a large hole that serves as the the overflow spillway that's easily visible near the dam. It's 87 feet in diameter. Though it's technically not a hole in the ground we still think it's worthy of mention.

Another large hole in the ground, though most of it is not readily visible, is Mammoth Cave. The Historic Entrance is located here: 37.188521, -86.105478

Mammoth Cave is the world's longest cave system with more than 365 mapped miles of passage.
