State by State
- Specimen Number
Rounded boulder of massive, brown, resistant sandstone. Verified by state survey.
Sedimentary. Sandstone. Arkose.
- Location & Occurrence
Staff says likely from the "red beds that occupy a northeast/southwest trend across central and northeastern New Jersey," part of the Newark Supergroup, rift-basin.
- Geologic Age
Triassic. There are no other rocks so undeformed that would qualify, though this seems unusually well cemented.
Newark Group associated with breakup of Pangea and correlated with rocks from Georgia to Newfoundland, including the Connecticut specimen stone (#6).
Specimen seems much harder and more cemented than the Newark Rocks from Connecticut. But the color and texture is otherwise identical.
