Laurence A. Jump was born in Oakland California in 1913. He learned to ski as a child and continued skiing at Phillips Exeter Academy and at Dartmouth College as a member of the ski team. Jump’s first job was with B. Altman, New York City as ski advisor in the sports department. In 1937 Jump left for Europe to travel. In Europe he took a job at the Informational Labor Office in Geneva. After the outbreak of World War II he left Geneva to join the ambulance service of the French Army in 1939. Jump was captured by the Germans during the invasion of France and released to the U.S. Consulate in Stuttgart, Germany.

Jump returned to the U.S. late in 1940 and was employed by Jones and Lamson Machine Company in Springfield, Vermont, until he volunteered for the ski troops in 1942. Jump enlisted during training and commissioned in November 1942. He was assigned to the mountain troops at the G-2 Intelligence school, Ada Infantry School. Jump participated in the Kiska invasion in 1943 and in 1944 was Second Lieutenant instructor for the 10th Mountain Division staff at Camp Hale. He was sent over to Italy with the 87th Mountain Infantry and fought at Mt. Belvedere in 1945. Jump was wounded and spent six months in the hospital. Once the war was over he returned to Colorado.

In 1946 Jump and F. S. Schauffler produced a ski survey for the Denver Chamber of Commerce. At this time the Forest Service was considering issuing a prospectus for the area with plans drawn by Ranger “Slim” Davis. In May of 1946 Larry Jump, Sandy Schauffler and Richard Durrance formed Arapahoe Basin, Inc. Jump was president, general manager and chairman of the board of directors. Richard Durrance and Max Dercum were vice-presidents, Sandy Schauffler was secretary/treasurer and Denver ski manufacturer, Thor Groswold, was director. The ski area opened for the 1946-1947 season.

Marjorie (Marnie) Brown was an avid skier and early investor in Arapahoe Basin. Jump met Marnie when she came out in 1947 to ski and work as a secretary for the ski area. Jump and Marnie were married in 1948 and had three children McClean, Patricia and Alice. Marnie contributed time and energy into developing the ski areas. After retiring Jump spent his spare time sailing and enrolled in a correspondence course in yacht design.

Through the development of Arapahoe Basin Jump met Jean Pomagalski, the manufacturer of a lift installed at Arapahoe Basin in 1953. Jean and Jump joined forces to start selling the ski lifts in the U.S. Jump phrased the name Pomalift and the company was incorporated in 1954. Pomalift sold 309 lifts in the U.S., 105 in Canada and 652 in France by 1966. On Jean’s advice Jump went to Italy to meet with Carlevaro and Savio the manufacturers of a sophisticated gondola lift system. Jump returned with a contract to represent the firm in the U.S. and coined the name Telecar for their business. Telecar was incorporated in 1957.

In 1957 Jump also incorporated Sell, Inc. which distributed rubber products, sailboats and rifles. Due to the large volume of Pomalift sales he incorporated Lift Services Inc. in 1959 to handle contract and maintenance services and sell parts for the Pomalift and Telecar lift systems. Jump was president of all four companies and responsible for sales, promotion, planning, new products and the liaison with France and Italy. In 1965 he merged Pomalift, Telecar and Lift Services under Mountain Lift Services and dissolved Sell, Inc. In 1968 Jump sold Pomalift to Jean Pomagalski and invested more time at Arapahoe Basin which sold the summer of 1972. Under new ownership the ski area was named A-Basin and Jump kept the title Arapahoe Basin, Inc. for investments the company held for stockholders.

Jump spent a lot of time developing another ski resort, Arapahoe East, which opened in the fall of 1972. Arapahoe East had problems due to management and leasing. In 1979-1980 he leased the ski area as Ski Golden. After that season Jump regained control and reopened as Arapahoe East once again. Jump retired from the ski business around 1986. He died in 1989.

Jump was a member of the Zipfelberger Ski Club, Faculty Club (founder), University Club and the Dartmouth Club of the Great Divide. He was active in the Rocky Mountain Ski Area Operators Association, past president of the Safety Committee, Americans Standards Association, National Forest Recreation Association and director for the Southern Rocky Mountain Ski Association. In the military he was awarded the French Croix de Guerre with Star, Bronze Star, Pacific and European Theater and Combat Infantryman.


The Larry Jump collection dates from Jump’s graduation at Phillips Exeter Academy in 1932 through to newspaper articles on Arapahoe Basin from 1997. The collection contains business papers and photographs documenting the various companies he initiated including Arapahoe Basin, Arapahoe East, Pomalift, Inc., Telecar, Inc., Lift Services, Inc., Sell, Inc. and Mountain Lifts.

The collection contains several documents from Jump's enlistment with the 10th Mountain Division which trained at Camp Hale in Colorado.

Larry Jump's involvement and opening of Arapahoe Basin is significant for many reasons. Jump was in charge of all policies, planning, publicity and acted as liaison with various organizations including the Forest Service, Arapahoe Lodge, Willy Schaeffler Ski School, contractors and ski organizations. Jump’s leadership accounted for Arapahoe Basin sponsoring the first National Senior Giant Slalom Championship in 1953, installing the first Pomalift in 1954; the first reserved ski system in Colorado in 1970; encouraging the use of ski bobs and holding the first championship race in 1972. Jump and Marnie were awarded the National Citizens Award by the Department of Defense for starting the first amputee skiing program in Colorado.

The series on Arapahoe Basin contains papers from 1946 to 1972 documenting the initial proposal, correspondence (including letters to potential investors), legal contracts, financial statements, invoices and receipts.

In the collection are documents of Willy Schaeffler. Originally from Kaufbeuren Bavaria, he was drafted into the German Army, then captured and tortured by the Russian Army. He escaped and worked for the Austrian resistance group for two years. In 1948 Jump received a letter from Willy Schaeffler inquiring about a position as ski instructor at Arapahoe Basin. Willy relocated to Denver and was hired as ski coach for Denver University. He was director of the Arapahoe Basin Ski School from 1948-1970. Willy kept busy as director of ski events at the 1960 Olympics, head coach for the U.S. ski team in 1970 and head coach for the 1972 Olympic ski team. Willy’s position at Arapahoe Basin Ski School drew many students and skiers to the area.

During the 1950s Jump started several business ventures. The largest amount of documentation is on Pomalift which he incorporated in 1954. Arapahoe Basin was the first ski area in the U.S. to have a Pomalift installed. Jump met Jean Pomagalski who designed this lift system. They went into business together and Jump became the first franchise in the U.S. to sell Pomalift equipment.

Jean Pomagalski S. A. of Grenoble France designed and fabricated surface lifts (both T-bars and disk types), chair lifts, gondolas and tramways. Jean Pomagalski S. A., one of the largest suppliers of lifts, was associated with the firm Applevage of France. Pomagalski improved and developed basic design features that evolved the fully automatic station. This enabled mass production methods to lift manufacturing and for the first time made a gondola lift economically feasible. By 1966 there were 1300 Pomalifts throughout the world. Mountain Lifts Corporation absorbed Pomalift in 1965 and in 1968 sold certain assets including the copyright to the name “Pomalift” to supplier Jean Pomagalski S.A. In 1970 Pomalift and Poma Aerial Tramways merged with Heron Engineering to form Heron Poma Co. Jump continued on as a sales agent for the lifts until 1970. The collection includes papers detailing the beginning of the company, extensive correspondence between Jump and Jean, project folders, correspondence with sales agents, legal documents, invoices, orders and financial records.

The collection documents Telecar and Lift Services, two companies developed due to Pomalift. Telecar was a company Jump started in 1957 that represented the Italian firm Carlevaro and Savio which designed a gondola lift system. Later when Savio made a chairlift for the U.S. there arose a conflict with Pomagalski and Cie and Jump discontinued representing the Italian firm. Later in the 1960s Telecar represented a Denver firm Miner Machine Co. that developed hydraulic chairlifts.

Lift Services was set up in 1959 to provide spare parts and service for Pomalift and Telecar systems. During this time Jump became interested in distributing products he came across through various companies and his personal interests. This led to the incorporation of Sell, Inc. in 1957. This company distributed rubber products, guns, sailboats and targets.

There are numerous documents on Jump’s personal life and family. Included in the collection is correspondence between Jump, his family and friends. Jump recorded his trip to Europe in 1936 and completed three journals. Later he wrote a twenty five chapter manuscript about the development and history of Arapahoe Basin. There are several folders of Marnie Jump material including correspondence and documents from her time with the Naval Reserve.
