In 1818 avalanching ice from this then advancing glacier blocked the river below, creating a lake that failed in what is now called the Gietro Flood. Today the river has been artificially dammed to generate hydroelectric power. https://images.squarespace-cdn.com/content/v1/636c0756500bb41c66a2b7a3/87838be4-7a2d-47a0-88c8-d63a0354d28a/rhone+glacierDSC04513-1024x680.jpg Adventures-Past and Present - Swiss Pioneers of the Ice Ages - Make it stand out Rhone Glacier with fabric to reduce melting over ice caves. https://www.robwesson.com/adventures/pierreabot-and-other-erratic-boulders monthly 0.5 2023-03-02 https://images.squarespace-cdn.com/content/v1/636c0756500bb41c66a2b7a3/8240751d-6980-48a8-a5c6-7d0962b10e9c/Plymouth_Rock_Plymouth_MA_jjron_03.05.2012.jpg Adventures-Past and Present - Pierrabot and Other Erratic Boulders - Make it stand out Plymouth Rock, perhaps the most famous glacial erratic boulder in the United States. The abundant evidence in supoort of the recent advance of glaciers in Canada and tne northern United States, led Canadian and America geologists to a relatively early adoption of the Swiss ideas about the Ice Ages.

(From Agassiz, Etudes sur less Glaciers, 1840). https://images.squarespace-cdn.com/content/v1/636c0756500bb41c66a2b7a3/e788a0a0-4e82-4470-a86d-d375ef06f587/Pierre-dBot.jpg Adventures-Past and Present - Pierrabot and Other Erratic Boulders - Make it stand out The Pierrabot, a glacial erratic near Neuchâtel, Switzerland. Louis Agassiz led a field trip to this site in 1837 following his presentation to a meeting of natural scientists. At the time almost no one believed his argument that this boulder had been transported to its current position by a glacier. https://images.squarespace-cdn.com/content/v1/636c0756500bb41c66a2b7a3/8be4a397-3a7d-4415-90b8-1ced2b8e41aa/MarmetteDSC04810.jpg Adventures-Past and Present - Pierrabot and Other Erratic Boulders - Make it stand out The Pierre des Marmettes, a glacial erratic in the parking lot of a hospital in Monthey, Switzerland. The erratic measures about 62 by 33 by 30 feet. The small house on top was constructed for the guards who surveyed the surrounding vineyards in the early 20th century. This and the other large surviving erratic boulders were only saved from quarrying for building stone by a public subscription campaign in the late 1800s. https://www.robwesson.com/adventures/the-unteraar-glacier monthly 0.5 2023-03-02 https://images.squarespace-cdn.com/content/v1/636c0756500bb41c66a2b7a3/17ed3483-4012-4804-b5f8-54d0b12436d8/Hugi-hu%CC%88tte2.jpg Adventures-Past and Present - The Unteraar Glacier - Make it stand out Rubbly medial moraine running down the center of the Unteraar Glacier as it appeared in 1840 with boulder tracked by Franz Hugi.
