Forest Service vegetation plot marker in old-growth forest near Spirit Lake, Mount St. Helens, 1979. Red and yellow striped survey pole with white sign reading "03 01 391" stands among tall conifer trees with blue-tinted undergrowth. This plot documented pre-eruption forest composition at the species level. Photo: USDA Forest Service, 1979.
Same vegetation plot location after May 18, 1980 eruption, showing complete devastation. Survey pole with sign reading "03 01 391" stands in gray ash-covered wasteland. All traces of old-growth forest erased by pyroclastic flows reaching 1300°F (700°C). Broken volcanic terrain visible in background under blue sky. Photo: USDA Forest Service, 1980.
The U.S. Forest Service documented this vegetation plot near Spirit Lake in 1979—a careful species-level inventory of an old-growth forest.
After May 18, 1980, they returned to the same coordinates and put up another marker. Same spot. Different planet.

Black-and-white line map titled “Time of First Ashfall, Pacific Northwest,” showing when ash from the May 18, 1980, Mount St. Helens eruption first reached locations across the region. Curving isochron lines labeled by hour spread east and northeast from the volcano in southwest Washington, crossing Washington and Oregon into Idaho and Montana, with an inset extending into Wyoming; small open circles mark observation stations and several cities are labeled, including Yakima, Spokane, Coeur d’Alene, Missoula, Great Falls, Billings and Cody. A legend notes the isochron times (Pacific Daylight Time, with Mountain Daylight Time in parentheses), and mileage/kilometer scales appear at upper left; the lower margin credits Dr. Michael M. Folsom and Dr. Robert R. Quinn (Department of Geography, Eastern Washington University), July 1980, issued as Plate 3 of Washington Department of Natural Resources, Division of Geology and Earth Resources open-file report (record series: Publications, State Government Agencies; collection: Natural Resources, Department of; statewide; reference No. 188-15489).
Old school #DataViz? In a way.
This WA Geological Survey plate map shows the time of first ashfall from Mount St. Helens on May 18, 1980.
Isochron lines show the ash cloud’s eastward push across the Pacific Northwest, stretching into the morning hours of Monday, May 19.

Surf's up! Hardy surfers at Whitley Bay yesterday evening. The sea temperature is around 8 degrees...so 10 degrees warmer than the air

I first encountered Castlefield as an architecture undergraduate in the late 80s/ early 90s and loved it. That feeling hasn't gone away.

Sex, drugs and the conscious brain: Francis Crick beyond the double helix
A thoroughly researched account of the history and relationships that shaped the scientist who co-discovered the structure of DNA.
Francis Crick, Nobel Prize winner who co-discovered the structure of DNA, "never had to teach or grapple with university administration: he applied for a grant only once in his life."

This project would suit an applicant with a background in ecology, physical geography, or the biological sciences. Experience of – and enthusiasm for - ecological field survey/sampling (preferably in a forested biome) is highly desirable.

A red Ford Pinto hatchback angles across a narrow gravel forest service road, a blue enduro motorcycle on a rear hitch carrier. Tall firs frame the view. Beyond them, a towering ash cloud from a pyroclastic density flow billows skyward. Photo by Richard Kent Lasher, May 18, 1980.
Tomorrow, we will talk about this photo.

A lot of great experiences on my recent trip to Australia. But swimming with humpback whales on the Ningaloo Reef was definitely one of the highlights.
