A group of Northwest scientists are sprinkling the landscape around Mount St. Helens with high-tech sensors as part of a new effort to map the volcano’s deep plumbing.

Scientists have a pretty good understanding of what’s happening right under the mountain, where a big chamber periodically fills up with magma before an eruption. Now they’re looking deeper — down dozens of miles — to the tubes and tunnels that feed that chamber.

Meanwhile, guests at hotels and campgrounds inside national parks have been told to leave by Thursday.

Just in time for another anniversary of the catastrophic Mount St. Helens eruption, the U.S. Forest Service is reopening an architecturally-striking visitor center. The Coldwater Ridge facility has been closed for the last four seasons. The center reopens next week with a new mission and purpose.

Coldwater Ridge was the first visitor center to open close to the volcano in the blast zone. That was in 1993. It was later eclipsed when another Forest Service visitor center -- Johnston Ridge Observatory -- opened even closer to the Mount St. Helens crater.
