It should be a great trip and I will post a photo report.
If anyone wants to join in, they're welcome. We could caravan to the camp from anywhere along I-15 from Utah County to Idaho Falls, or US 20 to Ashton (north of Rexburg) before we turn off towards camp.
I should be going through the following at about these times on Friday:
Salt Lake City: 1:00pm
Idaho Falls: 4:15pm
If you only want to hike to Union Falls, you can meet us at the Cascade Creek trailhead about a mile west of Grassy Lake http://s.tygr.ws/qOcRdZ (Google Maps). We'll likely be starting the hike between 7–8:00am Saturday. Look for my silver 2002 Saturn L200.
We'll be returning home Saturday evening after the hike.
PM me if you're interested and we'll exchange phone numbers.
