Don't know if anyone saw this on the GNP website Press Releases as of Monday, 5/22....they confirmed the three camp grounds affected:
"With the summer camping season approaching, Glacier National Park staff would like to remind campers that the Cutbank, Quartz Creek and Logging Creek campgrounds will all remain in “primitive” status this year. This means that no potable water is available at these locations. Campers should plan on bringing water from a safe source."
