It was a very mild winter, so most snow melted a month or more ahead of schedule, and by July 4th there was barely any to be found. I do know there's some still on Andrews Glacier in Rocky Mountain National Park. Don't go expecting pristine white fluffy stuff though. This pic was posted by the staff at Neptune Mountaineering on Facebook last week.
Here's a description of the trail: http://www.summitpost.org/andrews-glacier/159922
