Mineralogical Society

The Morris Museum Mineralogical Society (MMMS) was founded in 1971 to promote interest and education in the various earth sciences and, in particular, the subjects of geology, mineralogy, paleontology, lapidary and related subjects.

The MMMS meets at the Morris Museum at 7 p.m. on the third Thursday of the month, except in July and August. Most meetings, which are open to the public, feature a speaker who delivers an illustrated lecture.

The society also hosts Rock and Mineral Weekend on Thanksgiving weekend every year at the Museum. After many years of hosting the Gem, Mineral, and Fossil sale on the grounds of Delbarton School in Morristown, the show is now held in August on Museum grounds.
