Английская Википедия:Chip and Dale Towers
Шаблон:Short description Шаблон:Infobox mountain
Chip and Dale Towers are two Шаблон:Convert tall sandstone towers located in the Island in the Sky District of Canyonlands National Park, in San Juan County, Utah. Dale Tower rises to an elevation of Шаблон:Convert, whereas the lower Chip Tower is 5,420-feet. Airport Tower is set Шаблон:Convert to the southwest, and Dead Horse Point State Park overlook is situated Шаблон:Convert to the north-northeast. Chip and Dale Towers are an eroded fin composed of hard, fine-grained Wingate Sandstone, which is the remains of wind-borne sand dunes deposited approximately 200 million years ago in the Late Triassic. This Wingate Sandstone overlays a softer layer of the Chinle Formation. Access to the towers is via the four-wheel drive White Rim Road, and a scramble to reach the base.[1] The top of the towers rise over 1,000 feet above the road in approximately one-half mile. Precipitation runoff from Chip and Dale Towers drains east to the nearby Colorado River.
Climbing
The first ascent of 240-foot Chip Tower was made in October 1993 by Jeff Widen and Jeff Singer via Stuffin Nuts, (III, Шаблон:YDS, A2) on the south face.[2] The first ascent of 330-foot Dale Tower was made October 2, 1994, by Jeff Widen, Cameron Burns, and Jeff Singer, via Boy's Night Out, (III, 5.9, Al, 3 pitches).[3][4] The National Park Service temporarily closes access to these climbing routes to protect wildlife habitat for lambing desert bighorn sheep and nesting raptors season (March through August).[5]
Climate
According to the Köppen climate classification system, the towers are located in a Cold semi-arid climate zone, which is defined by the coldest month having an average mean temperature below Шаблон:Convert and at least 50% of the total annual precipitation being received during the spring and summer. This desert climate receives less than Шаблон:Convert of annual rainfall, and snowfall is generally light during the winter.
