Facilities for Big Four: the outhouse is pretty cute, looks like a hunter's shanty, was about as clean as a honey bucket. There is a covered pick nick area. Lots of information plaques. Large lawn where the Big 4 Inn used to be. Parking for around fifty vehicles. Dog-walk baggies are provided by Mount Baker State Park.
VerizonWireless Users: I lost cell reception a mile or so before driving past Robe Fire Station.
Condition of Mountain Loop Highway: as of March 13th (2010) the highway is clear and safe until you near Silverton. Motorcyclists, please watch out for the "Reduced Speed Ahead" sign. When you see it, reduce your speed immediately. Ten feet beyond said sign the asphalt has been removed in two areas and has been replaced with slippery gravel.
About five miles out of Silverton I encountered snow on the road. The road wasn't icy, but the snow was around four or five inches deep and I began to worry that my little Corolla wouldn't have enough ground clearance. I wouldn't suggest visiting the Big Four Ice Caves so early in the season unless you have an all-terrain vehicle of some sort. Or at least a car that sits more that six inches off the ground.
