El Diente Peak
El Diente Peak is a high summit in the San Juan Mountains range of the Rocky Mountains of North America. The peak is located in the Lizard Head Wilderness of San Juan National Forest, north by east ( bearing 8°) of the Town of Rico in Dolores County, Colorado, United States. "El Diente" is Spanish for "The Tooth", a reference to the shape of the peak. Climbing The topographic prominence of El Diente Peak is only , so by a strict cutoff rule, it would not be counted as a separate peak from its higher neighbor Mount Wilson. However, the 3/4 mile (1.2 km) connecting ridge is a significant climbing challenge ( Class 4/5), making El Diente more independent than its prominence would indicate. Hence, it is often regarded as a full-fledged fourteener. El Diente is one of the more dramatic peaks in Colorado in terms of local relief and steepness. As a result, it is one of the most challenging climbs among Colorado's fourteeners. All routes involve at least class 3 scra ...

Sea Level Datum Of 1929
The National Geodetic Vertical Datum of 1929 is the official name since 1973 of the vertical datum established for vertical control surveying in the United States, United States of America by the General Adjustment of 1929. Originally known as Sea Level Datum of 1929, NGVD 29 was determined and published by the United States Coast and Geodetic Survey and used to measure the elevation of a point above and Depression (geology), depression below mean sea level (MSL). NGVD29 was superseded by the North American Vertical Datum of 1988 (NAVD 88), based upon reference to a single benchmark (referenced to the new International Great Lakes Datum of 1985 local mean sea level height value), although many cities and U.S. Army Corps of Engineers "legacy" projects with established data continued to use the older datum. Methodology Mean sea level was measured at 26 tide gauges: 21 in the United States and five in Canada. The datum was defined by the observed heights of mean sea level at the ...

Lizard Head Wilderness
The Lizard Head Wilderness is a wilderness area in southwest Colorado. It contains and is jointly managed by the Uncompahgre and San Juan National Forests. It is southwest of the town of Telluride and is named for a prominent rock formation that is said to look like a lizard's head. Lizard Head itself is and is a volcanic spire of crumbling rock. Due to the steepness of the cliffs and the poor quality of the rock for fixing ropes, only experienced mountaineers should attempt to summit the spire. Another of trails in this infrequently visited wilderness, are also strenuous and should be attempted by more advanced backpackers. The area includes three prominent fourteeners: El Diente Peak (), Wilson Peak (), and Mount Wilson (). The area includes the headwaters of the west fork of the Dolores River The Dolores River is a tributary of the Colorado River, approximately long, in the U.S. states of Colorado and Utah. The river drains a rugged and arid region of the Colorado ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Colorado Fourteeners
This is a list of mountain peaks in the U.S. State of Colorado that exceed of elevation. In the mountaineering parlance of the Western United States, a ''fourteener'' is a mountain peak with an elevation of at least 14,000 feet. This is a complete list of the 53 fourteeners in the U.S. State of Colorado with at least of topographic prominence. See the main fourteener article, which has a list of all of the fourteeners in the United States, for some information about how such lists are determined and caveats about elevation and ranking accuracy. The summit of a mountain or hill may be measured in three principal ways: #The topographic elevation of a summit measures the height of the summit above a geodetic sea level. #The topographic prominence of a summit is a measure of how high the summit rises above its surroundings. #The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation. __TOC__ Fou ...

InReach
A Satellite Emergency Notification Device or SEND is a portable emergency notification and locating device which uses commercial satellite systems rather than the COSPAS-SARSAT satellite system. An example of this device is SPOT. The devices use an internal GPS chip to gather location information. When the SEND is triggered, this information is sent via commercial satellite to a commercial monitoring agency whose role is to pass the information to an appropriate responding agency. The responding agency contacted depends, in part, on the location. Examples of responding agencies would be military Search and Rescue, Coast Guard, local police, voluntary Search and Rescue. Typical users/purchasers of these devices are participants in activities such as hiking, mountain biking, climbing, boating and flying. They are also useful for those who work in remote areas (loggers, foresters, geologists, fisheries and wildlife staff). Additional features are increasingly being offered: sending p ...

Scree
Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. The term ''scree'' is applied both to an unstable steep mountain slope composed of rock fragments and other debris, and to the mixture of rock fragments and debris itself. It is loosely synonymous with talus, material that accumulates at the base of a projecting mass of rock, or talus slope, a landform composed of talus. The term ''scree'' is sometimes used more broadly for any sheet of loose rock fragments mantling a slope, while ''talus'' is used more narrowly for material that accumulates at the base of a cliff or other rocky slope from which it has obviously eroded. Scree is formed by rockfall, which distinguishes it from colluvium. Colluvium is rock fragments or soil deposited by rainwash, sheetwash, or slow downhill creep, usually at the base of gentle ...

Yosemite Decimal System
The Yosemite Decimal System (YDS) is a five-part Grade (climbing), grading system used for rating the difficulty of rock climbing climbing routes, routes in the United States and Canada. It was first devised by members of the Sierra Club in Southern California in the 1950s as a refinement of earlier systems from the 1930s, and quickly spread throughout North America. Description The class 5 portion of the class scale is primarily a rock climbing classification system, while classes 1–4 are used for hiking and scrambling. The current definition for each class is: ; Class 1:Hiking or trail running, running on a trail. ; Class 2:Simple scrambling, with the possibility of occasional use of the hands. ; Class 3: Scrambling. A rope could be carried. ; Class 4: Simple climbing, possibly with exposure (heights), exposure. A rope is often used. Falls could be fatal. Natural protection (climbing), protection can easily be found. ; Class 5: It is considered technical roped free climbing; ...

Topographic Prominence
In topography, prominence or relative height (also referred to as autonomous height, and shoulder drop in US English, and drop in British English) measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. The key col ("saddle") around the peak is a unique point on this contour line and the ''parent peak'' (if any) is some higher mountain, selected according to various criteria. Definitions The prominence of a peak is the least drop in height necessary in order to get from the summit to any higher terrain. This can be calculated for a given peak in the following manner: for every path connecting the peak to higher terrain, find the lowest point on the path; the ''key col'' (or ''highest saddle (landform), saddle'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting paths; the prominence is the differ ...

Absolute Bearing
In navigation, bearing or azimuth is the horizontal angle between the direction of an object and north or another object. The angle value can be specified in various angular units, such as degrees, mils, or grad. More specifically: * Absolute bearing refers to the clockwise angle between the magnetic north (''magnetic bearing'') or true north (''true bearing'') and an object. For example, an object to due east would have an absolute bearing of 90 degrees. Thus, it is the same as azimuth.U.S. Army, ''Advanced Map and Aerial Photograph Reading'', Headquarters, War Department, Washington, D.C. (17 September 1941), pp. 24-2/ref> * #Relative, Relative bearing refers to the angle between the craft's forward direction ( heading) and the location of another object. For example, an object relative bearing of 0 degrees would be immediately in front; an object relative bearing 180 degrees would be behind. Bearings can be measured in mils, points, or degrees.
