I found an error in the GeoTime loop instructions, page 55, #7:
"Veer left..": No: that keeps you in the forest. Strike that
whole sentence ending in "...under high transmission lines."
Follow the next sentence that starts "Your trail is still in the
forest for a short distance..."
Minor: In point #1: the parking lot near Sundew and Mayapple has
19 parking spaces, not 6.
In point #2: One millimetre of trail equals 1,000 years, not 100.
Sign #18 was not found by me on Sat Sept 7, 2024. Maybe it had
been vandalized and removed. I think it was sign #17, about the
Cretaceous Period, that had some black spray paint on it. It and
some of the other signs were quite faded; others were fresh and
new.
