the weather

I keep a daily log of the weather. Each morning around 7am I record sky cover, winds, and temperature. The record helps me later on while processing the meteorological data I collect by giving me a sort of ground truth. Here is a sample from this past week:

monday - clear, downvalley winds 10 to 18 knots, -1 C
tuesday - scattered, downvalley wind continued last night, -4 C
wednesday - scattered, upvalley winds, -4 C / increased winds and cloud level dropped in p.m.
thursday - overcast, calm, -5 C / light snow fell in mountains last night as low pressure passed
friday -overcast, calm, -6 C
saturday - scattered, calm, -6 C
sunday - clear, calm, -6 C

The season's melt had begun underway early in the week and was stalled by a passing low pressure. The small storm dropped light snow on the lakes and glaciers which hasall but shut down the melt. Our team is waiting for the melt to continue so we can conduct some salt tracer experiments on the cryolakes.

I spent a night at F6 camp for my Annual Fryxell Download and Maintenance Blitz. The Stream Team were great hosts . I completed maintenance on Explorers Cove, Lake Fryxell, F6 snow fence, and the soil stations. I spent a night sleeping 'under the stars' and the passing storm provided good sleeping temperatures.

The bad news of this past week is my camera broke (another lens error). So, no more photos for a while.

White River Glacier Station 983

The deep canyon below White River Glacier is the product of fire and ice. Volcanic eruptions, bulldozing glaciers, and lahars have created a raw and dynamic landscape on the southeast slope of Mount Hood. How fast is the landscape changing? Glacial moraines, often used to indicate past glacial extents, are heavily eroded or completely absent. Repeat historical photographs offer a view to how the canyon and the glacier has changed over the past 120 years. Harry F. Reid took two photographs from either side of the White River Glacier in 1901. These photos have the potential to assist with mapping the historical glacier perimeter but finding the location of the eastern photograph, frame 983, had vexed me during two previous visits. The photograph features the glacier terminus as viewed from the east with the top of the mountain obscured by clouds. In the foreground are two tree stumps, likely remnants of the ghost forest that formed by the Old Maid eruption in the late-1700s. The ty...

Glacier Rephotos from Mount Rainier

I posted a new batch of glacier repeat photos from Mount Rainier . Mount Rainier was quite an undertaking as it’s glaciers have been studied for a long time and there were many established photo stations.  Last September I traveled to the mountain as part of the Glacier Rephoto Database Project to document the photo stations and acquire new repeat photographs to record the changes. Last year was focused on the Glacier-clad Volcanoes of the Pacific Northwest. Nisqually Glacier, Station 5 Mount Rainier is a big mountain compared to the other volcanoes in the Pacific Northwest and equally big is the quantity of ice. The grandeur of the mountain and expanse of ice has attracted numerous glacier studies over the past century  including a number of  repeat photography projects. Perhaps the most studied is the Nisqually Glacier.  The glacier has undergone many changes over the past century. The three comparison photos from Station 5 illustrate the glacier a...

Rephotos of Mount Shasta Glaciers

I visited Mount Shasta on September 7, 2012 to reoccupy glacier photo stations established by Phil Rhodes in 1974. Phil is an expert on Mount Shasta’s glaciers and photographed the glaciers for several decades. I was fortunate to meet up with Phil for the first day of photographic surveys on Hotlum Glacier. Phil was invaluable in describing routes to stations and sharing his observations. I visited 10 of his stations at Hotlum, Bolam, Whitney, and Wintun glaciers over several days to record the station locations and rephotograph the scenes. Bolam Glacier: 1977 to 2012 The photo comparisons reveal the complex changes that have been occurring on Mount Shasta since the 1970s. Bolam Glacier receded, the Lower Wintun Glacier advanced, while others appear fairly stable. Past research has shown Whitney Glacier advancing since the 1950s through the early 2000s. The surface of Whitney Glacier appears to have lowered over the past 30 years from a photo station at 10,000 ft eleva...
