The green lush of WoGE#191 posted by Ron brutally misled me and apparently tricked others, too. After browsing through tropical rain-forests over the entire globe, I realized that being a little more flexible might actually pay off. Looking into the green patches of North America quickly turned out to be a good move - I landed in Kentucky's Mammoth Cave National Park in less than 15 minutes.
So I have the privilege to post the new WoGE puzzle. Frustrated by Ron's tricky post, I've first chosen something quite tough, but then figured I better keep that spot for later because I have this fine WoGE-worthy geomorphological feature I wanted to throw into the game long time ago. For those who are new to the game or haven't played for ages: to win, you must be the first to locate (lat-long) the image and describe it in geological terms as best as you can.
I consider this an easy deal, so I'll invoke the Schott Rule for this turn. That is, previous winners have to wait one hour for each of their wins before posting the answer.
