Farmfields are turned into wetlands after a levee was blown up. See the spectacular footage as we learn how it was done and why. Meet some of the folks who love to ride 500 miles across Oregon when we drop in on the 20th anniversary of Cycle Oregon. And it's a fascinating research project on submerged volcanic activity in the antarctic and how it relates to the Oregon Cascades.
