The state has no plans to excavate the Cambridge site, making research like Butz's important.
Butz believes it's the first time samples from the site have been tested for dating.
Richard Butz, a Pennsylvania-based travel agent with Cruise One, said he'll have no trouble selling trips on Quantum.
Butz said he plans to take his students to Indian Ovens to search for other evidence of Indian habitation.
Theresa Rebeck's drama, which also stars Norbert Leo Butz as Holmes' brother, had been scheduled to run until 24 February.
Butz said the six "ovens" formed naturally as a result of spherical deposits of quartz eroding out of the phyllite rock face.
Working with his students, Butz twice soaked the samples in a weak solution of hydrochloric acid to remove any contemporary soot stains.
The original production starred two rising musical theater stars: Norbert Leo Butz, who has since won two Tonys, and Sherie Rene Scott.
The original starred now-Broadway stalwarts Norbert Leo Butz and Sherie Rene Scott.
Butz first heard about the site when he began working for Cambridge Central Schools as an earth science teacher more than a decade ago.
Butz contacted scientists at a laboratory in Miami that specializes in radiocarbon dating who suggested he first conduct a simple test to determine if the soot stains occurred from more recent fires.
Butz said the Miami lab's radiocarbon tests recently revealed the fires that caused the soot stains occurred between A.D. 1410 and 1450, about two centuries before Europeans began arriving in the area.
Boy Scouts often hiked to the spot and built fires in the holes, so it wasn't known if the soot was from their visits or from use by Indians hundreds or even thousands of years ago, Butz said.
