- A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone. These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, and deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types.
- Wallace Falls State Park - Greg Ball Trail to Wallace Lake (wta.org)
The Greg Ball Trail is a trail envisioned by and honoring one of the greatest trail advocates this state has ever had. Ball was a former board member and director of the WTA. In 1993 he launched the organization’s volunteer trail maintenance program which has since grown into the largest state-based program of its kind. In 2004 at the age of 60, tragically, Greg passed away after battling cancer. He designed this trail to Wallace Lake and it was finished in his memory by volunteers from WTA and through support from the Spring Trail Trust.
