When it comes to natural beauty, nothing beats the majestic aspen. Who doesn’t love going up to the mountains to watch the aspens be ‘on fire’ in the fall? Their brilliant, yellow leaves contrast spectacularly with the cloudless, blue backdrop of a Colorado sky. They are truly one of Denver’s natural treasures. Sadly, many Denver residents are losing these treasures unexpectedly. Recently, we have received an alarming number of calls from folks who report their aspens are suddenly dying.
