Janet McConnell, U.S. Fish and Wildlife Service, measures stream flow in a Michigan river. She needs to know the rate of flow to determine a level of treatment of a lampricide.
My first attempt at long exposure water pictures. This is a dayime shot using a Cokin ND8 filter at the stream in my folks' back garden. I'd love to try this at night but whenever I'm there I'm usually pissed by dark.

Walking on the lava flow. Much of which is obsidian.
Newberry National Volcanic Monument was designated on November 5, 1990 to protect the area around the Newberry Volcano in the United States. It was created within the boundaries of the Deschutes National Forest and is managed by the U.S. Forest Service. It includes 50,000 acres (20,000 ha) of lakes, lava flows, and spectacular geologic features in central Oregon. These photos are taken from the summit Paulina Peak 7,985 ft, (2,434 m). Just below us are East Lake and Paulina Lake and The Big Obsidian Flow, created 1,300 years ago, covers 700 acres. It is hard to fathom as you drive through the summit area that you are within a 17 square mile caldera at the summit of a 500 square mile volcano, a volcano that remains very active to this day. Newberry is both seismically and geothermally active. Geologists believe the caldera sits over a shallow magma body only 2 to 5 kilometers deep. Visitors see numerous cinder cones (over 400 throughout the area), miles of basalt flows, as well as rhyolite flows of obsidian.
