Hepatica Hike - SOLD OUT
2026-04-12 13:00 - 15:30 | Crow’s Nest Preserve, 201 Piersol Road, Elverson, Pennsylvania, 19520
This event is sold out. Please join us at a future event.
Join event leaders on this off-trail exploration of a rarely visited section of the preserve. We’ll search the woods along Mine Run (a tributary of French Creek) to look for round-lobed hepatica, one of the earliest-blooming spring ephemeral wildflowers. Boulder-hop through Deep Woods to find other harbingers of spring like wood anemone, rue anemone, and early violets.
This part of the preserve has mature forest with diabase rock outcroppings. Though it looks pristine today, it has a long history of human use, including small quarry pits used to source cobblestones. A long-gone nearby railroad line (the Warwick branch of the Wilmington & Northern Railroad, once known as the Boar’s Back, today part of the Horse-Shoe Trail) is lingering evidence of this industrial period that extended into the early 20th century.
