32 Pa. Stat. § 5602
The General Assembly finds that caves are uncommon geologic phenomena and that the minerals deposited therein may be rare and occur in unique forms of great beauty which are irreplaceable if destroyed. Also irreplaceable are the archeological resources in caves which are of great scientific and historic value. It is further found that the organisms which live in caves are unusual and of limited numbers, that many are rare and endangered species and that caves are a natural conduit for groundwater flow and are highly subject to water pollution, thus having far-reaching effects transcending man's property boundaries. It is therefore declared to be the policy of the General Assembly and the intent of this act to protect these unique natural and cultural resources.
