I can’t be certain when the first of these two photographs was taken, but my gut feeling is 1995 or 1996. The second was taken this year.  I hadn’t set out this summer with the intention of recreating the earlier image (which explains the slightly different viewpoint), but while scrolling through my photographs recently, I realized I’d come very close to doing just that.  As in many of my previous time-and-again pairings, an obvious difference is in the growth and expansion of streamside willows.  Biologists generally attribute this to the reintroduction of wolves to Yellowstone Park, resulting in a decline of ungulate populations in the Park and surrounding country.  The pine tree on the right also shows growth, but considering the time differential between images it’s clear the growing season in these parts is pretty short.
