Probably best not to disturb it much. We have a commercial one south of me, a tourist attraction and former supply of ice to the town directly south, which could boast the coldest beer for miles around (and the hottest hookers, a popular rail stop) When they enlarged the entrance to harvest the ice back in the old days, it screwed up the airflow and the place melted out. So they covered it back up and restored the flow pattern inside. Shoshone Ice Cave, Idaho, pic related, now a tourist attraction.
