Is it Snowing!? When explaining dendrite this might cross your mind especially when adjectives such as “snowflake” & “frost” are used to describe this formation and it’s snowy white appearance. The reality is that “dendrites” are iron or manganese inclusions found on these white & colorless agates to create a wonderfully unique look that reflects the beauty of winter time. The term "dendrite" comes from the Greek word dendron, which means "tree".
