Yellowstone Lake Water Levels Can Tell Us More than You Might Think - USGS
Yellowstone Lake Water Levels Can Tell Us More than You Might Think A relatively simple measurement—lake level—has yielded big dividends in Yellowstone. By tracking the level of Yellowstone Lake over time, it is possible to understand more about a range of subjects, from the hydrology of stream flow to the physical properties of the magma reservoir beneath Yellowstone Caldera! Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Scott K. Johnson, Science Communication Associate the EarthScope Consortium. The strongest Yellowstone Lake seiche wave (primary mode) has a 78-minute period, but other weaker seiche waves are also present simultaneously. The importance of tide gauges is apparent to anyone who has lived near a coastline, but there are a host of reasons to measure the water level of inland water bodies, too. Sometimes that’s to monitor water cycle trends, like...
The Grand Story of the Grand Canyon of the Yellowstone - Caldera Chronicles
The Grand Story of the Grand Canyon of the Yellowstone Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Michael Poland, geophysicist with the U.S. Geological Survey and Scientist-in-Charge of the Yellowstone Volcano Observatory. The Grand Canyon of the Yellowstone is a natural wonder that almost defies description. The reaction of explorer Charles Cook when he first viewed the canyon in 1869 seems appropriate: “ I sat there in amazement, while my companions came up, and after that, it seemed to me that it was five minutes before anyone spoke. ” Sources/Usage: Public Domain.

A Christmas (misinformation) story: Yellowstone edition - Caldera Chronicles
A Christmas (misinformation) story: Yellowstone edition Misinformation and misconceptions about Yellowstone are nothing new. This past Christmas saw a particularly challenging episode of misinformation that caused widespread and needless concern—especially because there are many places on-line to find scientific information about Yellowstone’s current activity. Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Michael Poland, geophysicist with the U.S. Geological Survey and Scientist-in-Charge of the Yellowstone Volcano Observatory. On October 30, 1938, Orson Welles directed and narrated a live radio adaptation of the H.G. Wells novel The War of the Worlds . The incident is famous for supposedly having incited a panic that the events being described were really happening. Some people apparently thought that Martians were invading Eart...
