This MODIS Aqua 1-km-resolution, true-color satellite image shows a resuspended ash cloud generated from high winds scouring the dry, unvegetated deposits in the Valley of Ten Thousand Smokes. The cloud stretches across Shelikof Strait to western Kodiak Island.
Location: south-central Alaska, from Kodiak to Anchorage

Remnants of a spruce forest complex following a severe wildfire in the Yukon Flats National Wildlife Refuge, Alaska. Wildfires are the dominant landscape-scale disturbance operating at annual time scales in Alaska, and fires play a major role in the rate and extent of vegetation growth and productivity of a site.

The avian paramyxovirus is found across the planet, infect wild and domestic birds, and sometimes lead to disease outbreaks, but according to a new study led by the USGS, wild ducks and shorebirds do not appear to carry these viruses, which can lead to Newcastle disease that sickens or kills poultry.
