Title: Information Sheet, Chesapeake & Ohio Canal National Historical Park, 19 December 2004



Chesapeake & Ohio Canal National Historical Park, 19 December 2004

On 19 December 2004, the Maryland Native Plant Society took a field trip to Chesapeake & Ohio Canal National Historical Park in Montgomery County, Maryland.   Our leaders were John Parrish and Rod Simmons.   It was an overcast day, and the temperture hovered around 34 degrees F.   We were dry during our trip because there was a slight drizzle before our trip which started at about 10:30 a.m., and it rained soon after our trip ended at about 3 p.m.   Direct sun occurred during our lunch break.   Some of the things that we saw are illustrated below.   I thank our trip leaders and others who taught us about the biota.
