This 1932 postcard both shows the camp and provides a description of the location. 

The Highway 1 described on the postcard seems to refer to Minnesota Trunk Highway No. 1, which opened in 1924, and was the first portion of the Duluth-Twin Cities road to be paved on the northern side. It connected West Duluth to Esko's Corner in Carlton County. As a News Tribune story states, quoting a Duluth Herald story from July 16, 2924, "Highway 1 extended from 59th Avenue West along a 'new low-grade climb over Thomson Hill, doing away with the steep hill formerly in use. From Esko's Corner, contractors are now laying the pavement to Carlton.'" 

The Tribune story also notes that "A chunk of old Highway 1 still snakes up into the woods above Kingsbury Creek, however. It's blocked off to motorists by large boulders."

As Waferdog notes, that would seem to put the camp somewhere near the present Thompson Hill Scenic Overlook.
  

Also as noted in the News Tribune story, the road is no longer open to car traffic but a stretch of it still exists above I-35 for anyone who wants to take a walk in search of remnants of the Kum Bak Tourist Camp.
  

As marked by the circle and x in the image below, the camp location above and the rest point location identified by Waferdog are a little more than a half mile from each other on Thompson Hill, matching the information on the postcards.
  

I guess so. And in that spirit I'll add in this photo. Maybe it will end up somewhere 100 years from now and someone will enjoy trying to make some sense of it.
