Rock Glen Conservation Area, on the Ausable River in Arkona, Ontario, Canada, is renowned for its Devonian-era fossils dating back 350 million years. The adjacent Ausable Gorge was first inhabited by paleo-people over 6000 years ago. This slide show features sinuous images of the glen’s 10.7 metre waterfall, riverscapes, landscapes, and foliage close-ups. “Sanctum,” composed and performed by Rapoon, provides an insistently rhythmic musical track with aboriginal overtones. Quotes by Dion Boucicault, Lao Tzu, Henry David Thoreau, Francois Rabelais, Delmore Schwartz, and Eric Woolfson compare the river’s flow with time’s passage.
