A mineral is defined as a solid of inorganic origin with a constant chemical composition and definite physical properties
Rocks are defined as a solid composed of one or more minerals
Therefore, ice may be considered a mineral and/or a rock composed of a single mineral?
(Ill leave that issue to those far more intelligent to figure out) 🙂
At any rate, I thought these icicle-like forms along the North Fork were interesting whether they are rock, mineral, or just frozen water
Formed when the water was at a higher level and froze in the cold air as the water receded??
