Spelunker - Trials Rising: Sixty Six DLC

Navigate the underground caves of "The Petrified Forest" - 10

This is done on the track: "The Petrified Forest" - Arizona, USA

I recommend using the Mantis.

At the start of the track, you need to reverse backwards into the entrance of an abandoned mineshaft. Where you need to roll backwards off the ledge onto another ledge below, then slowly go forward off the edge onto another ledge. Then backwards onto the ledge below that. Another forwards onto the ledge below that. And then forwards onto the ledge below that one. And backwards onto the ledge below. And lastly, forwards onto the last ledge below.

You can then pick up a Sixty Six Squirrel which is waiting for you, continuing out off the cave you will magically appear at Checkpoint 1.

The Petrified Forest National Park in Arizona has been made famous for the Petrified Logs, Fossils and Geological Rock Formations. Petrified Wood is a fossilized log or tree which has all of the organic structure replaced by rock over hundreds of thousands of years.
