GSW spring field trip: Mather Gorge (in memory of E-an Zen)

GSW Spring Field Trip

Geology of the Great Falls of the Potomac:

A field trip and picnic in memory of E-An Zen

Saturday, June 14, 2014

Led by Phil Justus, Rockville Science Center

In his 50-year career as a geologist with the USGS and University of Maryland, E-An Zen (1929-2014) had a wide-ranging impact and influenced many other geologic careers. E-An’s last major topic of research was the geomorphological evolution of the Potomac River gorge area at Great Falls. To honor his memory, Phil Justus, who participated in Zen-led field trips 30 years apart, will lead a geology walk from Great Falls Tavern to Mather Gorge. The walk will be followed by a potluck picnic in or near the tavern, where friends of E-An will be invited to share their memories. Note: participants are welcome to skip the hike and just join us for the picnic after the hike.

Meeting time and place: 9:00 AM, Great Falls Tavern, C&O Canal National Historic Park (Maryland side)—rain or shine. Park fee is $5 per vehicle.

What to wear and bring: suitable clothes and footwear for a 2.5-hour hike over rocky terrain, and portable chairs, food and drink for the picnic.

Following the hike: we will meet around noon to eat lunch and share our memories of E-An. We may be able to use an upstairs room in the tavern, but should be prepared for an outdoor picnic as well.

RSVP: please email Bill Burton ( beforehand if you plan to attend or have questions—please indicate whether you are interested in both the hike and picnic, or just one or the other. On the day of the trip: please call Phil on his cell phone, 301-717-5887301-717-5887,if you plan on attending just the picnic (location may change), or are running a little late for the hike,or are cancelling last minute.
