Every summer the Arctic ice cap melts down to what scientists call its “minimum” before colder weather builds the ice cover back up. The size of this minimum remains in a long-term decline. The extent on August 26, 2012 broke the previous record set on September 18, 2007. The line on the image shows the average minimum extent from the period covering 1979-2010, as measured by satellites. According to scientists from NASA and the National Snow and Ice Data Center, the 2012 melt season could still continue for several weeks.

Sometime in August crews working on the Blue Lake hydro project in Sitka will shut off the old penstock from the dam and connect a new one -- work that will leave the town without its drinking water supply for up to four months. In the meantime, the city is returning to its former water plant on the Indian River, but it’s not a matter of turning a few valves. Because of higher drinking water standards, Sitka has rented a temporary filtration plant -- at a cost of about $1-million per month. more
Sitka Fine Arts Camp director Roger Schmidt and development intern Melissa Campbell discuss the camp's Restoration Internship Program. Twenty-six college students from around the country are working to save the former Sheldon Jackson College laundry, aka "Smokestack Building." Learn more about the Save It or Lose It campaign
