Mt. St. Helens 2024

A week ago, we traveled up to southwest Washington State to go to the Mt. St. Helens Volcanic National Monument. We watched the eruption and subsequent ash clouds on May 18, 1980 and on from our home then in Vancouver, WA. We have pictures from that time.
The drive was beautiful and the information centers were informative. This all brought back memories. The Johnston Ridge Observatory and Spirit Lake were off limits due to a road landslide which will be another 2 years to repair. Harry Truman who lived at Spirit Lake and lost his life there that Sunday is buried under 150 feet of volcanic ash and mountain slide plus lake level.

Newberry Volcano

Have you ever heard of the Newberry Volcano?
The shield-shaped stratovolcano is located about 20 miles south of Bend, Oregon, and is one of the largest and most hazardous active volcanoes in the United States.
It is designated as a “very high threat” volcano in a recent assessment by the U.S. Geological Survey, as are the Big Island volcanoes of Mauna Loa and KÄ«lauea.
Newberry Volcano has been active for more than 530,000 years, most recently 1,300 years ago.

Lava flows erupted at Newberry cover an area larger than Rhode Island. Powerful explosive eruptions sent volcanic ash into Idaho and the San Francisco Bay Area. A deep caldera indents its summit, hosting a flow of obsidian and thick beds of explosive pumice…
Newberry Volcano formed at the western end of the High Lava Plains, a broad volcanic region of basalt and rhyolite in southeastern Oregon that forms the northern sub-province of the extensional Basin and Range Province, best known in Nevada.
A link to the story is here.
