A bit erratic perhaps, but darn pretty.
Two tourists were hiking in the Chequamegon-Nicolet National Forest.
“I wonder where all these rocks came from?” - One tourist asked.
“Well,” said the other tourist. “I hear the glacier brought 'em.”
“So where is the glacier now?” - The first tourist asked.
“I guess it went back for more rocks.” – Was the reply.
Geologists have their faults (bada boom) but no one can accuse them of lacking a funny streak.
