COLVILLE RIVER, ALASKA– The science has reached the home stretch now, as has the entire summer’s field effort. We got a break in the cloudy weather last night, and sat around a fire labeling sample bags and weighing/organizing samples... {Read More »}

COLVILLE RIVER, ALASKA-- We awoke this morning to rain, wind, and 35? F temperatures. Immediately the remaining sampling lost most of its appeal, but we inhaled our coffee and oatmeal and staggered forth through the wet brush and tussock tundra... {Read More »}

COLVILLE RIVER, ALASKA– Days drift by on the river. The wind of the previous entry indeed subsided that evening, and we paddled from 11 PM to 5 AM, stopping for an hour to gape in awe at a massive exposure of permafrost (frozen ground) towering above the river... {Read More »}

COLVILLE RIVER, ALASKA– Finally, there is time to journal, as we are still relaxing in the “Salix Lounge” (Latin genus for willow). We’ve spent 36 hours watching the river flow backward – upriver. It has granted us time to catch up on some of the scientific literature, so we’ve been discussing the changes underway in North Slope river floodplains... {Read More »}

COLVILLE RIVER, ALASKA-- Aha! Windstorm #2, and we have ducked into some willows after the wind halted our downriver progress. This morning was crisp and clear, but the wind produced swells and breaking waves moving upriver... {Read More »}

COLVILLE RIVER, ALASKA-- Another day of fieldwork and floating later, we are camped on a big bend in the Colville, across from cliffs and peregrine falcons. Yesterday saw more science, including clear evidence of shrubs colonizing alpine tundra... {Read More »}

COLVILLE RIVER, ALASKA-- The four-person crew for this second float of the summer is led by Greta Myerchin and myself, both veterans of the first trip (Nimiuktuk/Noatak) and familiar with the science and wilderness protocols... {Read More »}
