The county history of 1883 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

The federal wildfire occurrence database lists 18 fires within 5 miles of Glass Rock between 2007 and 2020, burning about 19 acres in total. None started naturally. None was recorded as arson. Distance is straight-line from the map coordinates, so a fire counted here may appear on a neighbouring settlement's page as well.

The most recent of them, most recent first, with the day each was reported and the service that recorded it.

Settlements close enough to share some of these fires:

• Chalfants
• Glenford
• Yost
• Walser
• Ziontown
• Mount Perry

Every fire recorded in Perry County

Museums hold 196 specimens collected within 10 miles of Glass Rock between 1892 and 1975: 187 Animalia, 5 Plantae, 3 Fungi, 1 Protozoa. 12 distinct Species records are shown. Collected by Bergstrom, J., Buchanan, J., Buker, W.E. and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.

Matched on this settlement's Geographic Names Information System number rather than its name, so it cannot be a different place of the same name in another state.

This settlement is recorded in the Geographic Names Information System as feature 1061098.
