"A unique aspect of Lasting Impressions is that not all of its stories come from professional surveyors." Rhonda Rushing explains, "I thought it would be great to include geocachers and benchmark hunters, because I've become increasingly aware of their activities in finding survey monuments and reporting the markers to the National Geodetic Survey (NGS). It seems like a fun activity that honors surveyors' work in an interesting way."

"Increasingly, efforts by individuals from the popular pastime of geocaching are playing a significant role in the attempt to preserve and protect these essential components of our national infrastructure."
– Dave Doyle, NGS
