Glaciation in Columbia Mountains and Rocky Mountains in Canada

Lee-side Frontogenesis in the Rocky Mountains

The development and motion of fronts associated with lee-side troughs on large mountain barriers has been investigated. These fronts differ from ordinary cold fronts in their horizontal temperature field, which is characterized by a sinusoidal thermal ridge. The thermal ridge intensifies, while remaining stationary with respect to the mountains, and moves eastward upon the approach of a Pacific...

Gas Resources and Production in the Rocky Mountains

Natural gas demand in the United States has been increasing for the last 15 years and is expected to increase substantially in the next 20 years (Energy Information Administration, 2003; National Petroleum Council, 1999). Demand is projected to increase in all sectors, especially electricity generation (Figure 1.1). In fact, 80 percent of projected electricity generation capacity additions thro...

Late Holocene environmental change at treeline in the northern Coast Mountains, British Columbia, Canada

An integrated stratigraphic, paleoecological, and geochronological study of lake and fen sediments just beyond the terminus of Berendon Glacier provides insights into late Holocene climate, vegetation, and glacier change in the northern Coast Mountains of British Columbia. Cores collected from two small lakes in the foreland of Berendon Glacier and pits dug in a nearby fen record Little Ice Age...

Changing Climate Suitability for Forests in Yellowstone & the Rocky Mountains

Wood dynamics in headwater streams of the Colorado Rocky Mountains

[1] An 11-year monitoring study begun in 1996 evaluates wood mobility in five Colorado Rocky Mountain streams. Each channel reach is 40–70 m in length. Initial surveys included channel dimensions and arrangement of each piece of wood. Annual resurveys focused on wood arrangement and persistence. Average diameter of 15 cm and length of 3.2 m varied little among sites. Average yearly mobility ran...
