A natural stone arch in south Mason Valley near Yerington, Nevada. The name is informal. It's after the late Alvin McLane, a naturalist with the Desert Research Institute. The arch was featured in an episode of the PBS program "Wild Nevada" about 20 years ago, where Alvin was the guide on the program.

Just across the canyon from the Sego Canyon rock art site, Sego Canyon, Grand County, Utah. It's in the Cretaceous Blackhawk Formation (Willis, Utah Geol. Min. Surv., Map 89, 198) and is evidently unnamed, without so much as an interpretive sign. I'm sure, tho, the local Native Americans had stories about it--I find it hard to imagine the proximity of the rock art is a coincidence!

Unnamed rock arch in sandstone directly across the road from the Sego Rock Art site. I'm sure the Native Americans had stories about it--I find it hard to believe the proximity of the rock art is a coincidence!--but there's not so much as an interpretive sign. The arch is in Cretaceous Blackhawk Formation, according to the mapping of Willis (Provisional Geologic Map of the Sego Canyon Quadrangle, Grand County, Utah, Utah Geol. Min. Surv. Map 89, 1986). You can walk up the drainage to directly below the arch (inset).

Yours truly on the West Gemini Bridge near Moab, Utah. It's both perfectly safe and perfectly legal!

To get the picture of the West Gemini Bridge. The reason there is so much rock in the foreground of that pic is that I was standing _well_ back from the edge! For more about the Gemini Bridges see the enclosing photo.

West Gemini Bridge on the left; East Gemini Bridge on the right. The Gemini Bridges are a twinned set of arches on BLM land near Moab, Utah. Alas, there have been a number of Darwin Awards due to idiots attempting to jump between the arches. See enclosing photo for more information.

Looking east; the other (east) bridge is hidden behind this one. The Gemini Bridges are a twinned set of arches on BLM (Bureau of Land Management) land near Moab, Utah, accessed by a rough dirt road (high clearance mandatory and 4WD desirable!) Because they're not in a national park, the regulations aren't so stringent, and not only is it perfectly safe to stand on the arches, it's perfectly legal (left inset). I would have liked to get a picture standing on the arch from here, but I was by myself and my remote release isn't _nearly_ long enough ;) I suppose if I'd had a radio-controlled one-- The middle inset shows the overhanging ledge I'm standing on to get this picture, and the right inset shows the gap between the arches. I don't have a picture like this of the east arch because it would require being on the far side of the canyon, and I had no time for such a sidetrip! The arches are in the Jurassic Wingate Sandstone, according to Doelling et al.'s map (Utah Geological Survey, Map 155, 1994). Unfortunately, there have been a number of Darwin Awards from idiots attempting to jump between the arches.

Off the southern Oregon coast. A more oblique view than that in the enclosing photo. The island directly behind is Yellow Rock; the farther island to the right, with two summits barely visible, is Mack Arch. The small rocks to the right of it form Mack Reef. Mack Arch is supposed to be the biggest on the Oregon coast, but we're at the wrong angle here to even see the arch!

Not the most imaginative name-- Off the southern Oregon coast. The island directly behind is Yellow Rock; the farther island to the right, with two summits barely visible, is Mack Arch. The small rocks to the right of it form Mack Reef. Mack Arch is supposed to be the biggest on the Oregon coast, but we're at the wrong angle here to even see the arch! The inset shows an oblique view of Arch Rock.

Back toward the camera position in the enclosing photo. Painted Hills, north of Reno, Nevada.

Natural arches in volcanic rock (rhyolitic ash-flow tuff) in the Painted Hills, north of Reno, Nevada. This unit is notable for cavernous weathering! Insets show (left) a close-up of the lower window; and (right) a view back out this window looking toward this camera location.

View from the other side.

An extraordinary natural arch in heavily jointed, cavernous weathering granite. The insets show a couple of different views, one showing more of the surroundings, and the other a silhouette taken from the other side. Pershing County, Nevada. Anywhere else this would be a park with interpretive signs and entry fees; here it's just out in the middle of nowhere, accessible only by Jeep roads.

Over (yes!) Spanish Creek, a tributary of the Feather River, California, USA. It's crossed by California State Route 70, which here is parallel to the original Feather River route of the Western Pacific railroad, now part of the Union Pacific system. Looking roughly southeast.

Burro Creek in the foreground, swollen and muddy from the monsoon rains. US 93 crosses this bridge between Kingman and Wickenburg, outside the small town of Wickieup. Arizona, USA. There is a BLM (Bureau of Land Management) recreation site and campground here.

On Interstate 82 near Yakima, crossing the canyon of Selah Creek.
