Red Cliffs, Washington County, Utah - January 2013

When the weather is not so good in northern Utah in January, you can always head south where the sun is usually shining. Here are a few photos I took on my way home from a conference in St. George, Utah at the Red Cliffs Recreation Area and preserve. Also included are a few pictures of the rocks around the Quail Creek reservoir.

Historic Orson Adams home. The home was built between 1862 and 1865. Orson Adams was a veteran of the Mormon Battalion. The Adams house is the only intact structure that remains of the short-lived Mormon pioneer settlement of Harrisburg.

Pine Valley Mountains, a granite intrusion, in the rear with the Red Cliffs in front. The granite intruded into the area about 20-21 million years ago, warping up the surrounding rock layers. This type of intrusion is called a laccolith.

Virgin anticline (fold) at the north end of the Quail Creek reservoir. The thin sandstone cliff capping the top of the hills is the Shinarump Conglomerate Member of  the Triassic Chinle Formation. The darker red and lighter striped red and gray rocks below are the Upper Red Member and Shnabkaib Member of the Triassic Moenkopi Formation.

Exposures along the west side of Quail Creek reservoir of the Triassic Moenkopi Formation capped by a thin ledge of Shinarump Conglomerate. The dark brick red rock layers are the Upper Red Member of the Moenkopi and the lighter reddish pink and gray layers are the Shnabkaib Member of the Moenkopi, where the gray layers are mostly gypsum.
