Ancient Colorado river flowed backwards
(PhysOrg.com) -- Geologists have found evidence that some 55 million years ago a river as big as the modern Colorado flowed through Arizona into Utah in the opposite direction from the present-day river. Writing in the October ...
Flow in Earth's mantle moves mountains: study
If tectonic plate collisions cause volcanic eruptions, as every fifth grader knows, why do some volcanoes erupt far from a plate boundary?
At last, a theory about why Denver is a mile above sea level
Geologists may finally be able to explain why Denver, the Mile High City, is a mile high: water.
Researchers explore climate impacts on Wyoming's Bighorn Basin populations over the last 13,000 years
(Phys.org)—During the past 13,000 years, Wyoming's Bighorn Basin has experienced significant increases in population growth—due primarily to periods of high effective moisture and moderate temperatures—according ...
2001-2002 drought helped propel mountain pine beetle epidemic, study finds
A new University of Colorado Boulder study shows for the first time that episodes of reduced precipitation in the southern Rocky Mountains, especially during the 2001-02 drought, greatly accelerated development ...
Hibernation altered by climate change takes a toll on Rocky Mountain animal species
Climate change is causing a late wake-up call from hibernation for a species of Rocky Mountain ground squirrel and the effect is deadly.
Mountains, seaway triggered North American dinosaur surge
The rise of the Rocky Mountains and the appearance of a major seaway that divided North America may have boosted the evolution of new dinosaur species, according to a new Ohio University-led study.
Geoscientists discover trigger for past rapid sea level rise
The cause of rapid sea level rise in the past has been found by scientists at the University of Bristol using climate and ice sheet models.
Curvy mountain belts
Mountain belts on Earth are most commonly formed by collision of one or more tectonic plates. The process of collision, uplift, and subsequent erosion of long mountain belts often produces profound global effects, including ...
Mystery of monarch migration takes new turn
During the fall, hundreds of millions of monarch butterflies living in eastern North America fly up to 1,500 miles to the volcanic forests of Mexico to spend the winter, while monarchs west of the Rocky Mountains fly to the ...
New research discovers metabolic adaptation to high altitudes
When mammals are cold, they can employ physical changes to stay warm -- such as intense shivering. Like any form of aerobic exercise, though, "shivering thermogenesis" is especially challenging at high altitudes ...
Colorado mountain hail may disappear in a warmer future: study
Summertime hail could all but disappear from the eastern flank of Colorado's Rocky Mountains by 2070, according to a new modeling study by scientists from NOAA and several other institutions.
Nitrogen from humans pollutes remote lakes for more than a century
Nitrogen derived from human activities has polluted lakes throughout the Northern Hemisphere for more than a century and the fingerprint of these changes is evident even in remote lakes located thousands of ...
Snowpack declines in Rockies unusual compared to past
(PhysOrg.com) -- The researchers evaluated the recent declines using snowpack reconstructions from 66 tree-ring chronologies, looking back 500 to more than 1,000 years.
