Get a closer view

You kick some sand out of your shoes and ease up towards the altar, feeling a little edgy. As you get closer to it you see that it is indeed a small scale replica of Stonehenge, only the top of the stones is stained a blackish color that doesn't seem at all like paint.

1. You go up to the altar and touch the stained altar with the tip of a forefinger
2. You backtrack the way you came
3. You notice little mushrooms growing at the base of the altar
