Understanding Pacific Northwest (U.S.) mountain climbers’ motivations: Mount Baker, Washington, and Mount Hood, Oregon

Historical Glacier and Climate Fluctuations at Mount Hood, Oregon

Terminus fluctuations of five glaciers and the correspondence of these fluctuations to temperature and precipitation patterns were assessed at Oregon’s Mount Hood over the period 1901–2001. Historical photographs, descriptions, and climate data, combined with contemporary GPS measurements and GIS analysis, revealed that each glacier experienced overall retreat, ranging from 62 m at the Newton C...

Spatial and morphological change on Eliot Glacier, Mount Hood, Oregon, USA

Eliot Glacier is a small (1.6 km) glacier on Mount Hood, Oregon, USA, and its ablation zone is largely covered with rock debris. We examine the interrelated processes of ablation rates, ice thickness and surface velocities to understand the retreat rate of this glacier. Since measurements began in 1901, the glacier has retreated 680m, lost 19% of its area and thinned by about 50m at the lower g...

Ecological Zones: A Hike Up Mount Washington

A Multi-Year Longitudinal Study of Water Quality Parameters in Four Salmon-Bearing and Recreational Streams on Mount Hood, Oregon

Four streams-Clear Fork, Lost Creek, Camp Creek and Still Creek-in northwestern Oregon's Sandy River Basin were monitored for temperature, dissolved oxygen levels, and fecal bacterial concentrations in a multi-year analysis examining stream health for recreational users and anchor habitat for Pacific Salmon. Temperatures were recorded using micro -T temperature loggers at 15 locations, during 2...

The physiologic cipher at altitude: telemedicine and real-time monitoring of climbers on Mount Everest.

Advanced wearable biosensors for vital-signs monitoring (physiologic cipher) are available to improve quality of healthcare in hospital, nursing home, and remote environments. The objective of this study was to determine reliability of vital-signs monitoring systems in extreme environments. Three climbers were monitored 24 hours while climbing through Khumbu Icefall. Data were transmitted to Ev...
