John Reppy
John David Reppy (born February 16, 1931) is a physicist and the John L. Wetherill Professor of Physics Emeritus at Cornell University. He studies the quantum properties of superfluids such as helium. Reppy is also a notable rock climber of long standing. He established a number of widely known climbing routes particularly in the northeastern United States. Early life and education John David Reppy was born February 16, 1931 in Lakehurst, New Jersey. His father was stationed at the US Naval Air Station, where he worked with helium as a lifting gas for naval lighter-than-air aviation. The family moved almost every year to follow his military placements, including an assignment to Pearl Harbor prior to World War II. In 1943 he was sent to the western Pacific and the rest of the family settled in Haddam Neck, Connecticut. In Connecticut John Reppy became interested in herpetology, geology and rock climbing, exploring local quarries. He graduated from high school in 1950. ...

Herpetology
Herpetology (from Greek ἑρπετόν ''herpetón'', meaning "reptile" or "creeping animal") is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians (gymnophiona)) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the scientific study of birds is the subject of ornithology. Thus, the definition of herpetology can be more precisely stated as the study of ectothermic (cold-blooded) tetrapods. Under this definition "herps" (or sometimes "herptiles" or "herpetofauna") exclude fish, but it is not uncommon for herpetological and ichthyological scientific societies to collaborate. Examples include publishing joint journals and holding conferences in order to foster the exchange of ideas between the fields, as the American Society of Ichthyologists and He ...

Alps
The Alps () ; german: Alpen ; it, Alpi ; rm, Alps ; sl, Alpe . are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across seven Alpine countries (from west to east): France, Switzerland, Italy, Liechtenstein, Austria, Germany, and Slovenia. The Alpine arch generally extends from Nice on the western Mediterranean to Trieste on the Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at is the highest mountain in the Alps. The Alpine region area contains 128 peaks higher than . The altitude and size of the range affect the climate in Europe; in the mountains, precipitation ...

Maine
Maine () is a state in the New England and Northeastern regions of the United States. It borders New Hampshire to the west, the Gulf of Maine to the southeast, and the Canadian provinces of New Brunswick and Quebec to the northeast and northwest, respectively. The largest state by total area in New England, Maine is the 12th-smallest by area, the 9th-least populous, the 13th-least densely populated, and the most rural of the 50 U.S. states. It is also the northeasternmost among the contiguous United States, the northernmost state east of the Great Lakes, the only state whose name consists of a single syllable, and the only state to border exactly one other U.S. state. Approximately half the area of Maine lies on each side of the 45th parallel north in latitude. The most populous city in Maine is Portland, while its capital is Augusta. Maine has traditionally been known for its jagged, rocky Atlantic Ocean and bayshore coastlines; smoothly contoured mountains; heavily f ...

Mount Katahdin
Mount Katahdin ( ) is the highest mountain in the U.S. state of Maine at . Named Katahdin, which means "Great Mountain", by the Penobscot Native Americans, it is within Northeast Piscataquis, Piscataquis County, and is the centerpiece of Baxter State Park. It is a steep, tall massif formed from a granite intrusion weathered to the surface. The flora and fauna on the mountain are typical of those found in northern New England. Katahdin was known to the Native Americans in the region and was known to Europeans at least since 1689. It has inspired hikes, climbs, journal narratives, paintings, and a piano sonata. The area around the peak was protected by Governor Percival Baxter starting in the 1930s. Katahdin is the northern terminus of the Appalachian Trail and is near a stretch known as the Hundred-Mile Wilderness. In 1967, Mount Katahdin was designated as a National Natural Landmark by the National Park Service. The mountain is commonly called just "Katahdin", though the of ...

Cannon Mountain (New Hampshire)
Cannon Mountain (formerly Profile Mountain) is a peak in the White Mountains of New Hampshire. It is known for both its technical rock and ice climbing on its cliff face and skiing at Cannon Mountain Ski Area. It was also home to the Old Man of the Mountain, until that formation collapsed on May 3, 2003. Cannon has three sub-peaks with heights of 3,693, 3,700, and 3,769 feet (1,125, 1,127 and 1,148 m), collectively known as " The Cannon Balls". Geologically, it is an exfoliating granite dome. Part of the Kinsman Range, the mountain is within Franconia Notch State Park. History Rock climbers were pioneering routes on Cannon's cliffs in the 1920s. Its ski area is one of the oldest in North America. Trails had been cut on the mountain prior to 1933, but the mountain gained widespread recognition that year when the Taft Slalom was cut as the first racing trail in North America. The mountain gained lift service with the construction of the first aerial tramway in North America, in ...
