Supplemental material: The Earth Has a Future

Geosphere, May 2006, v. 2, p. 113-124, doi: 10.1130/GES00012.1. Animation 3 - Cross-section along the international boundary showing the retreat of Niagara Falls to 30 k.y. in the future, based on the interpretation of Philbrick (1974). A retreat rate of 900 m/yr is assumed until the retreat of the present falls stops (14 k.y. from now in the figure). Resistant dolostone is in gray; non-resistant, mostly shaly rocks are in green. Water is in blue. The undercutting beneath the falls is exaggerated for effect. File size is 0.1 MB. Note: These are animated .gif files. If the animations are appearing as static images, try viewing them with a movie player.
