By: Esther M. Kingsbury-Stewart, Paul K. Link, Carol M. Dehler, and Shannon L. Osterhout The Kings Peak 7.5-minute quadrangle straddles the crest of the Uinta Mountains in the High Uinta Wilderness Area and contains Kings Peak, Utah’s highest point. The peaks and cliffs are comprised of the newly formalized formations of the Neoproterozoic (late Precambrian)
Grizzly Peak is the highest point in Oakland, at 1754 feet elevation (sources differ). As you approach it on Grizzly Peak Boulevard, it seems to loom quite high. That’s an illusion caused by the eucalyptus forest. As you get closer, you start to see through the trees. And from the bay side, the peak has
In response to my failure to measure the Earth before (See post here for background and details) I again attempted to measure the Earth using the length of the shadows during the the days before and after the summer solstice. To recap here is the background:~2200 years ago, a man named Eratosthenes made a pretty good estimation of the size of the Earth using the length of shadows during the summer solstice at two different locations.To repeat this experiment there are some [...]
The glacially carved cliffs around Camp Lamoille are truly spectacular — and while we were, now nearly a month ago — they provided us with constant fascination and wonderment amid the ever-changing light and cloud effects. To the south of us, besides Ruby Spire and the Wolf's Ear (seen in this earlier post), Mt. Gilbert towered over us at 11,120 feet.

In the low desert of southern Utah these days, when mid–September temperatures not only approach triple digits but also have the audacity to linger there, it is time to head to the high country for a hike along the redrock near Cedar Breaks National Monument. It never hurts to bring along a few friends. Judy points out the blazes, so we must be going in the right direction. Soon views emerge of Cedar Breaks and the 50–million–year–old lake and river deposits of the Claron Formation. [...]

Mount Cook rock avalanche 1991. Lloyd Homer, GNS ScienceOn 14th December 1991 a massive rock avalanche occurred from the East Face of Aoraki /Mount Cook, sending an estimated 14 million cubic metres of rock in a 1.5 kilometre wide cascade across the grand plateau and down onto the Tasman Glacier. It is thought that the avalanche travelled at speeds of 400 to 600 km per hour, and the resulting seismic recording at Twizel, 75 km away, lasted well over a minute, registering the [...]

The most recent of my science failures involves me trying to measure the size of the Earth in the method of Eratosthenes. If you don't know his tale, basically it was this: ~2200 years ago a man named Eratosthenes lived in Egypt. He noticed that the shadows were different lengths based on his location at the same time of day at the same time of year (the summer solstice). He saw that at noon in one location (Alexandria) there was no shadow and at the same time and date at another location [...]
It was 60 years ago today when Edmund Hillary and Tenzing Norgay reached the top of the world's highest mountain, the first ever to do so. They did it because it was there, but Hillary also collected rocks along the way. So today, 60 years ago, a piece of Earth's highest point entered the database of science.
John McPhee wrote in Basin and Range about that moment and that rock, "When the climbers in 1953 planted their flags on the highest mountain, they set them in snow over the skeletons of [...]

I’m in final preparation for a rafting exploration down the Green and Colorado Rivers in Canyonlands National Park with geologist Wayne Ranney, his geological entourage, and Colorado River and Trails Expeditions. In substitute for one of my regular posts, I offer a few views taken "here and there" on the Colorado Plateau.Traveling north on the Cottonwood Canyon Road through the Kodachrome Basin, this spectacular scene is barely three miles from Cannonville, Utah on Scenic [...]
Geology and Landforms on and from Cleeve Hill, CheltenhamSaturday 29th June. 10.00 am – 5.00 pm.Dr. Nick Chidlaw The imposing plateau country that rises E of Cheltenham to the highest point of the Cotswolds, affords spectacular views and contrasting landscapes all around. A circular 4-mile walk, slowly-paced and mostly on the level (some steep-slopes), will take you around Cleeve Hill with frequent stops to examine features such as the geology of limestone quarries (see photograph), and [...]
For this week's benchmark, I thought I'd share one of my favorites: the USGS marker on the highest point in my undergraduate field area, the Fish Lake Plateau in Utah. Fish Lake itself, which sits in a graben, is bounded by Mytoge Mountain on its southeast side and the Fish Lake Hightop on the northwest. The Hightop is accessible from the Pelican Canyon Trail, which leads you over a moraine and up a lovely glacial
Pershing Drive sits at the top of the south end of the Piedmont block at nearly its highest point, just under 800 feet. At one end of the road is a long exposure of rugged Franciscan chert that is exquisitely integrated into the landscaping, which includes native oaks as well as the usual plantings. It
The image above is based on data from the Indian Oceansat-2 satellite and shows that on 12 July 2012 virtually all of the Greenland ice sheet surface was melting. The highest point on the ice sheet, Summit at 3,200 meters saw temperatures at 36 degrees! The melt areas can be detected by the albedo of the ice sheet and this can be confirmed by a network of automated surface stations
Here on the northern hemisphere the daylight is now becoming shorter and shorter, and this will go on until winter solstice (22 December 2011 at my location). The rate at which sunrise times are becoming later is surprisingly enough not the same as the rate at which sunset times are becoming sooner (at times one of the two may actually be shortening, while the other is lengthening, although to a lesser degree). Earth's orbit around the Sun is not circular but elliptic. Owing to this fact [...]
The Mulanje district in the Southern Region of Malawi is known for its tea growing industry and for Mount Mulanje which is one of the highest peaks in Southern Africa. The soils, climatic conditions and sloping ground of the area around the impressive Mount Mulanje are well suited to the tea crop that supports up to 10,000 smallholder farmers. The temperatures in Malawi are however rising steadily, and more frequent droughts and floods are affecting more and more people. A rising number of [...]
A backdraft explosion from The Gray MonkToday's CNN news reports on a backdraft explosion at a fire in Ohio. This type of explosion can occur when an oxygen-starved fire suddenly gains access to oxygen, for example when a window breaks or a door is opened. It is a dangerous and well-known phenomenon for firefighters. An oxygen starved fire produces combustible gases, primarily carbon monoxide, and smoke. When these gain access to oxygen, combustion can take off again raising the [...]
This week’s Friday Field Photo is of Cerro Aconcagua, the highest peak in the western hemisphere at 6,962 meters (nearly 23,000 feet). Aconcagua is in the Andes mountains not far from Mendoza, Argentina, and very close to the continental divide and international border with Chile (32°39′12.35″S; 70°00′39.9″W). I went to a conference in Mendoza in
