Polar Bears!

Posted by Laurie Frost on May 17, 2010

While browsing at the US Geological Survey’s photo collections, I thought I’d have a look around, and what I found in its Animals album are some more polar bear images for you. Based on blog stats, public domain images of polar bears are popular, so add these to the three posts of mine that featured the bears last year (one, two, three).

Interestingly, a number of these shots were credited to a Coast Guard photographer, so I thought I’d have a look there, too, and while I was at it, check to see if the US Fish and Wildlife Service had any new pictures.

Lesser Known Volcanos of the USA

Posted by Laurie Frost on April 20, 2010

Next month marks the 30th anniversary of the eruption of Mount St. Helens in Washington State. But did you know that in the United States alone there are 169 volcanoes defined as active by the U.S. Geological Survey and that 54 of these are considered to pose a threat to the public?  Here’s a map of the 169 from the U.S. Geological Survey [USGS], which is also the source of  the map’s caption, as well as the other public domain images and information in this post.

The U.S. Geological Survey (USGS) is responsible for monitoring our Nation’s 170 active volcanoes (red triangles) for signs of unrest and for issuing timely warnings of hazardous activity to government officials and the public. This responsibility is carried out by scientists at the five volcano observatories operated by the USGS Volcano Hazards Program and also by State and university cooperators.
