Shot this at Turtle Rock climbing area near St. George. It was snowing in Salt Lake City, but down here it was warm and sunny. The cottonwoods hadn't even lost their leaves yet and it was mid November. The climb up the prominent prow on the right is a classic 5.11b/12a called Banana Dance. We all put in a lot of time hanging on it and having fun. |

There is a wayside rest with restrooms and a parking area on top of the bluff with stairs down to a beach at the site. Its location at the head of Lake St. Croix, the broad, slow area of the river that stretches from Stillwater to Prescott, Wisconsin, where the St. Croix joins the Mississippi River, is undeveloped and features many islands and tall sandstone bluffs on either side of the river. |

Only few fungi growing on soil (Lias sandstone) in this spruce forest. A few nests of A. mellea are on wood of Picea abies. |

Many fungi on a Fagus sylvatica tree fallen on Lias sandstone soil - near Moutfort, east of Luxembourg city. |

An incised meander of the Colorado River near Page, AZ. (The river has cut down the steep gorge by erosion.)
Same vantage point as http://gigapan.org/gigapans/33145/, but taken with a "cheap camera from WalMart" (no autofocus/exposure lock, lower megapixels, less zoom). Makes for an interesting comparison. [Why did we do this? Short version: I left my camera in the car and it was a 1.5 mile roundtrip hike to get it. Figured we could pan in the meantime...] |

One of two pans of Horseshoe Bend, a lovely incised meander near Page, Arizona (just east of Glen Canyon Dam).
Erosion by the Colorado River cut down through the layers of sedimentary rock and created the deep gorge (approx. 1000 feet deep here). [We also took another pan from the same point (http://gigapan.org/gigapans/33155/) with a different camera.] |

Layers of wet sediment were disturbed (those are the saggy layers in the red rock), forming a large pipe that quickly filled with sand. Once lithified (formed into a rock), the layers erode more easily than the pipe of sand, which is often left behind as a large chimney of sandstone.
(I need to get some more concrete information on this process, but that's the general idea...) |

At this point (between Escalante and Boulder), Rte. 12 in southern Utah crosses along the top of a ridge with drop-offs to both side, exposing expanses of Navajo sandstone occasionally cut by canyons. |
