The Adventure of Adventurely Adventuring!

Ah, such a beautiful day. The sun is shining! The birds are singing! And only a few people are being mauled by the 3-headed winged demons which dominate the sky.

You are on a hiking trail in Yosemite, and enjoying yourself greatly, when suddenly you hear a rumbling. Looking up, you see a rock-slide coming your way. You quickly dive off the trail and tumble down a rocky slope, yet miraculously, you emerge without a scratch on you (thank heavens for convenient plot devices.) Upon looking around, you realize you are completely lost. There is an enormous rock face to your right, on which is a mysterious wooden door. To your left is a small pond, and in front of you a densely forested area.
