Historical fire in sagebrush landscapes of the Gunnison sage-grouse range from land-survey records
Gunnison Tunnel: Engineering History of an Early American Reclamation Project
This paper describes the surveying, engineering, and construction operations performed in the construction of the Gunnison Tunnel for the Gunnison River Diversion Project. The Gunnison Tunnel, which diverts water from the Gunnison River to the Uncompahgre Valley, was one of the first major engineeri
A post–6 Ma sediment budget for the Colorado River
Regional sediment budgets provide a useful method for quantifying erosion by large river systems over geologic time scales. The Colorado River (western United States) is well suited for such an analysis because the eroding source (Colorado Plateau) and sediment sinks in transtensional basins of the
Colorado River chronostratigraphy at Lee's Ferry, Arizona, and the Colorado Plateau bull's-eye of incision: REPLY
Karlstrom et al. (2013) raise two issues in their Comment related to aspects of the discussion in our paper (Pederson et al., 2013) about the Lee’s Ferry record and incision in the Colorado Plateau. We synthesize evidence for the bull’s-eye pattern of incision over the past 105 yr, finding that it d

LA-ICP-MS analysis of quartzite from the Upper Gunnison Basin, Colorado
From ignimbrite to batholith, northeastern San Juan Mountains, Colorado<subtitle>Bonanza, Cochetopa Park, and North Pass calderas</subtitle>
The Southern Rocky Mountain volcanic fi eld contains widespread andesite and dacitic lavas erupted from central volcanoes; associated with these are ~26 regional ignimbrites (each 150–5000 km3) emplaced from 37 to 23 Ma, source calderas as much as 75 km across, and subvolcanic plutons. Exposed pluto
New views on late Paleozoic climate and tectonics in the Ancestral Rocky Mountains
Recent research in Pennsylvanian-Permian strata of the Fountain Formation adjacent to the Front Range uplift and the Cutler Formation adjacent to the Uncompahgre uplift (Colorado) has resulted in new hypotheses about the climate and tectonics of the Ancestral Rocky Mountains. The Fountain and the Cu
Gone with the shining things
The lure of gold in the great reefs of Johannesburg near the end of the 19th century not only attracted the famous mining barons such as Cecil John Rhodes, Alfred Beit and Barney Barnato: working men also came from far and wide to feed their families with their labour.Among them was my great-grandfa
An analysis of whirling disease risk in Western Montana
Myxobolus cerebralis, the causative agent of whirling disease, has been a major contributor to the loss of young trout in numerous streams within the Intermountain West (Colorado, Idaho, Montana, Utah, Wyoming). Currently there are no effective management procedures for mitigating the effects of thi
Patterns of natural avalanche activity associated with new snow water equivalance and upper atmospheric wind direction and speed in the mountains surrounding Gothic, Colorado
Snowfall, temperature and wind are three factors that quickly change avalanche conditions. Ridge-top winds have been used to assess avalanche conditions with mixed success due to high variability. Few analyses have tested the effect upper atmospheric winds have on avalanche conditions. This study at
