The vegetation units on this map were determined through a series of image processing steps including unsupervised classification, ecological modeling and stereoscopic interpretation of aerial photographs supported by field sampling and ecological analysis. The vegetation boundaries were identified on the photographs by means of the photographic signature and collateral information on slope, hydrology, geography, and vegetation in accordance with the Standardized National Vegetation Classification System (October 1995). The mapped vegetation reflects conditions that existed during the specific year and season that the aerial photographs were taken. There is a margin of error inherent in the use of aerial photographs....

Colorado National Monument, Colorado. Devils Kitchen, looking north from a ridge in the middle of No Thoroughfare Canyon. An erosional remnant of the Wingate Sandstone capped by the lowermost sandstone of the Kayenta Formation. Photograph by T.F. Giles, December 15, 1978. Figure 57, U.S. Geological Survey Bulletin 1508.

Colorado National Monument, Colorado. Ladder Creek Monocline and Redlands Fault. View is northwest from a point near Little Park Road east of the monument. No Thoroughfare Canyon in the foreground, which is bordered on the left by northeastward-dipping beds of Wingate Sandstone at the northwest end of Ladder Creek Monocline. Old Serpents Trail, the lower part of which is barely visible, ascends this dipping block of rock. The dark Proterozoic rocks form the flat-topped bluff on the right and are exposed by the Redlands Fault which lies just above the sharply upturned remnants of the Wingate Sandstone. 1976. Figure 29, U.S. Geological Survey Bulletin 1508.

Colorado National Monument, Colorado. Looking northeast from Old Serpents Trail, before 1950, when the trail was still used by cars and trucks. One of John Otto's old foot trails joins the old road at the lower middle. A lens of sandstone about 50 feet thick in the Salt Wash Member of the Morrison Formation begins just around the corner near the base of the high bluff across No Thoroughfare Canyon and is seen extending as far to the left as the normally dry wash that drains the canyon. When water flows down the wash after thunderstorms or from melting snow, the sandstone lens takes in water (recharge) which moves slowly down the dip of the lens to the northeast and supplies several artesian wells. In turn, the light...

Colorado National Monument, Colorado. Summerville Formation at Artists Point. The base of the formation rests upon Moab Member of Entrada just beneath the pavement. Top of the Summerville here has been removed by erosion. May 25, 1970. Figure 20, U.S. Geological Survey Bulletin 1508.

Colorado National Monument, Colorado. North wall of the arm of Monument Canyon. Gradational contact between the Wingate Sandstone and the Kayenta Formation. Erosional unconformity between Kayenta and overlying Entrada Sandstone is also shown. Normally a bench-former as on the right, the Kayenta on the left forms part of a single cliff. Wingate Sandstone, Kayenta Formation, Entrada Sandstone, Morrison Formation, and Summerville Formations. Circa 1950. Figure 10, U.S. Geological Survey Professional paper 451.

Colorado National Monument, Colorado. Kodels Canyon Fault, looking northwest across the mouth of Fruita Canyon from a point on Rim Rock Drive. Here, along a normal fault dipping steeply northeastward, the 350-foot cliff of Wingate Sandstone on the upper left has been sheared and squeezed into only a few feet of broken rock overlain by a steep slope of the Kayenta Formation covered by pinon and juniper. The thinner cliff on the right is the Entrada Sandstone which belongs high atop the cliffs on the left. Book Cliffs form the distant skyline on the right. May 29, 1970. Figure 31, U.S. Geological Survey Bulletin 1508.

Colorado National Monument, Colorado. Geologic structural features at the north end of the Monument. Scale is approximately #1:25,000. The three stereoscopic pairs may be viewed in turn without optical aids by those accustomed to this procedure or by use of a simple double-lens stereoscope. Geologic features may be identified by comparison with the appropriate part of Plate 1 in this professional paper, orienting map with north to the left. Kodels Canyon Fault; upper bend of Lizard Canyon Monocline; Redland Fault; and upper bend of Fruita Canyon "monocline". Photo by U.S. Soil Conservation Service. Figure 34, U.S. Geological Survey Professional paper 451.

Colorado National Monument, Colorado. Fruita Canyon, looking northeast from a point on Rim Rock Drive above the head of the canyon. Dark Proterozoic rocks floor the canyon, above which are the slopes of the red Chinle Formation and the cliffs of Wingate Sandstone capped by the lower resistant beds of the Kayenta Formation. Beyond the Grand Valley are the dark Book Cliffs and the more distant, light-colored Roan Cliffs. May 28, 1970. Figure 45, U.S. Geological Survey Bulletin 1508.

Colorado National Monument, Colorado. Kayenta Formation, showing lenses of hard channel sandstones and wedge of red siltstone and mudstone, along the road cut of Rim Rock Drive near the head of the main stem of Ute Canyon. Vertical grooves remain from drill holes used in blasting the road cut. Figure 14, U.S. Geological Survey Bulletin 1508.
This data set contains imagery from the National Agriculture Imagery Program (NAIP). The NAIP program is administered by USDA FSA and has been established to support two main FSA strategic goals centered on agricultural production. These are, increase stewardship of America's natural resources while enhancing the environment, and to ensure commodities are procured and distributed effectively and efficiently to increase food security. The NAIP program supports these goals by acquiring and providing ortho imagery that has been collected during the agricultural growing season in the U.S. The NAIP ortho imagery is tailored to meet FSA requirements and is a fundamental tool used to support FSA farm and conservation programs....

Colorado National Monument, Colorado. Petrified Sand Dunes in Wingate Sandstone along Old Serpents Trail. View is north across the Redlands and Grand Valley to the Book Cliffs. Battlement Mesa on the right skyline. 1976. Figure 10, U.S. Geological Survey Bulletin 1508.

Colorado National Monument, Colorado. Northwest end of Redlands Fault, passing through the col to the left of updragged remnants of the Chinle Formation and Wingate Sandstone. The fault, which here is normal, ends against unbroken Lizard Canyon Monocline in the next canyon to the northwest. View is west from a point just south of Wingate Drive a few hundred feet west of South Broadway. 1976. Figure 41, U.S. Geological Survey Bulletin 1508.

Colorado National Monument, Colorado. West into Monument Canyon, from a curve on Broadway just northwest of the end of South Broadway, showing Independence Monument. Redlands Fault ends in this canyon. Lizard Canyon Monocline can be seen on the extreme right. 1976. Figure 42, U.S. Geological Survey Bulletin 1508.
