Attended as a parent-chaperone with a well behaved middle school group. The staff member in charge of the stamp mill was unprofessional and rude. He gave essentially no instruction or information and did not allow the kids to ask any questions. The man in charge of the panning experience was not as rude as the stamp mill employee. However, he was dismissive and impatient. There is very little interaction required on the part of the mine staff in general and this would have been a big part of it. For an experience that should have been very interesting an informative, it turned out to be a big disappointment. I would not recommend this for any school group or field trip.
