Michael Martin will discuss his most recent trip to Nepal, a trek to Gokyo Lakes in the Khumbu region. The highest freshwater lake system in the world, Gokyo Lakes offers visitors access to views of the highest mountains in the world, without the press of the highly traveled route to Everest Base Camp. Michael will also briefly discuss his past trips to Nepal, and offer tips to those considering a future visit.

Known as the book that turned millions of high school students off hot dogs, "The Jungle" was originally published in the socialist newspaper "Appeal to Reason" after muckraking journalist Upton Sinclair spent seven weeks working incognito in Chicago's infamous meatpacking plants. A realistic depiction of the struggles and harsh conditions of plan workers and the corruption of powerful people in charge, the descriptions of health issues and unsanitary practices prompted the passage of sanitary reforms such as the Meat Inspection Act. Sadly, the concerns of the book feel increasingly relevant today.

**This talk has completely sold out in advance and no door tickets will be available.** [Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“The Course of the Appalachian Trail,”** on the fascinating past and uncertain future of a beloved wilderness trail and national park, with Mills Kelly, emeritus professor of history at George Mason University and author of *A Hiker’s History of the Appalachian Trail.* [Advance tickets: $13.50 plus sales tax and processing fees, available at [https://events.ticketleap.com/tickets/profsandpints/appalachian-trail](https://events.ticketleap.com/tickets/profsandpints/appalachian-trail) .] Spring brings people flocking back to the Appalachian Trail, which for more than 100 years has provided opportunities to spend anywhere from a few hours to six months traversing the Appalachian Mountains. Stretching more than 2,000 miles across 14 states, from Springer Mountain in Georgia to Mount Katahdin in Maine, it ranks among the most iconic long-distance hiking trails in the world. It and its associated national park are annually visited by nearly 17 million. Gear up for Earth Day—and perhaps some time on the trail yourself—by spending an evening with Mills Kelly, an expert on all things Appalachian Trail and is the author of two books and numerous articles on the trail’s history. We’ll start our scholarly journey by looking at the trail’s origins. First proposed by Benton MacKaye, a forester, in 1921 as a place for urban workers to get some fresh air and sunshine, the trail took 16 years to scout, map, and carve out of the mountains. The first version was woven together mostly from abandoned mountain roads, Indigenous people's paths, and highways. Drawing on research in archives up and down the length of the trail, Professor Mills will show us archival photographs and video clips spread across the decades of the trail’s history, and he'll let the voices of hikers themselves describe how the experience of hiking has changed over the decades. You’ll earn what hikers ate before the advent of freeze-dried backpacker meals and when and why thru-hiking became a thing. More profoundly, we’ll examine how innovations in gear changed the experiences of women on the trail, and how changing attitudes about race transformed the hiking community. Professor Mills will describe how the trail is maintained entirely by 33 volunteer clubs, including the D.C. area’s Potomac Appalachian Trail Club, founded in 1927 to help build it. Looking ahead, he’ll discuss how the trail’s long-term health as a recreational resources is being affected by declining federal support, overuse in some sections, and climate change. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Doom and Dinosaurs,”** a look at how mass extinctions shaped the dinosaurs and what research on these events tells us about Earth life’s long-term prospects, with Ian Wilenzik, paleontologist and visiting assistant professor of biology at George Washington University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-doom-and-dinosaurs](https://events.ticketleap.com/tickets/profsandpints/dc-doom-and-dinosaurs) .] Pity the poor dinosaurs. They lacked both scientific research to help deal with potential environmental catastrophes and places where they could have a beer and discuss it. You, on the other hand, have the opportunity to come to Profs and Pints to hear a fascinating talk on the impact of mass extinctions on dinosaur evolution and what research on dinosaurs tells us about biodiversity and Earth’s current biodiversity crisis. Dr. Ian Wilenzik, who has studied and taught courses on dinosaur evolution, population spread, and extinction, will leave you with a greater appreciation of the resilience of life on earth and how we’re both the product and source of biologically catastrophic events. Many of us are familiar with how a big meteor impact about 66 million years ago wiped out the Earth’s dinosaur population, leaving us only with their feathered descendants, birds. Less well known is how the Earth actually has undergone five periods of mass extinction that wiped out nearly all life, and how dinosaurs arose from one and endured another—both caused by volcanic activity—before meeting their match in the third. To ground his discussion, Dr. Wilenzik will talk about how we study mass extinctions by looking for geologic evidence of volcanic activity, meteoric blasts, and other catastrophic activity and of gaps in the fossil record after them. He’ll also discuss what makes a dinosaur a dinosaur, describing their distinct anatomical features. He’ll talk about how they and other forms of life evolved over long periods of time and were affected by extinction events. We’ll look at how the meteor-caused mass extinction that wiped out dinosaurs at the end of the Cretaceous paved the way for the rise of mammals and the emergence of primates, and, eventually, us. Looking ahead to future mass extinctions and what might survive them, we’ll talk about how that plant you forget to water might have the last laugh, as well as why crocodiles might be around a while. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

This is one of my fav hikes that combines very scenic valley and river views. We'll start with the Gold Mine trail which runs along the bluff above Great Falls. We'll then hike the Billy Goat A trail, which is one of the most scenic hikes in Maryland. A large part of this hike is scrambling over boulders and rock faces. It is a challenging hike that has very scenic views of the river. The total distance will be 6 miles with about 500 feet of elevation gain. We'll hike at a slightly faster pace, and it should take about 3.5 hours. This hike is not for beginners. Please only RSVP if you hike or walk at least 6 miles per week at a faster pace. If you can't keep up, we will leave you behind, so it's your responsibility to know the route and how to get home on your own if you have to. After the hike, we might go grab a bite at Fish Taco, 7945 Macarthur Blvd, Cabin John, MD 20818 Parking: \-\- The closest place to park is in one of the small lots on the left side of MacArthur Blvd directly across the street from Old Anglers Inn\. But these lots are often full\. \-\- The best place to park is on the street on Stable Lane\. Stable Lane is just past Old Anglers Inn on the right\. \-\- You will also see a lot of cars parked on MacArthur Blvd even though there are "No Parking" signs\. I've never seen anyone towed or ticketed for parking on MacArthur Blvd\, but you're on your own there\. Note that this event is cross posted with the Fast and Fun Hikers meetup group. Hope you can join us! \*\*\* IMPORTANT \*\*\* BY ATTENDING THIS EVENT, YOU AGREE TO THE LIABILITY WAIVER, INDEMNIFICATION, ASSUMPTION OF RISK, AND OTHER TERMS AND CONDITIONS ([https://drive.google.com/file/d/1Z39AGebAVz9c-3S4zf3tj4Eb7V9k3PrH/view](https://drive.google.com/file/d/1Z39AGebAVz9c-3S4zf3tj4Eb7V9k3PrH/view)) (revision 12/1/22).
