  • Chronology of Snowmaking Notes for 2001 Exhibit, New England Ski Museum by Jeff Leich
    Chronology of Snowmaking Notes for 2001 Exhibit, New England Ski Museum by Jeff Leich The following notes on snowmaking are intended to aid in the development of a Ski Museum exhibit. In many cases it is unclear from the sources referenced below exactly when a particular machine or practice was first invented or instituted. It is also probable that sources with data on certain early inventions were not located. It is therefore not possible to determine which machine or practice was "the first" of its kind; rather, this chronology is intended to indicate the general sequence of the development of snowmaking for skiing. 1934 "A novel experiment was attempted by the Toronto Ski Club 'Board of Strategy' when faced with the opening of their new jump with a major competition and no snow in sight. An excellent substitute for snow was provided in the form of shaved ice....made arrangements with the University of Toronto skating rink to have their ice planer work overtime...Several trucks were employed to haul the pulverized ice to the jump, a distance of about four miles...Seventy-five tons were cut and delivered within a few hours. This was sufficient to cover the entire hill from tower to outrun, with about six or eight inches on the landing slope....it was from ten to twenty percent faster than dry snow, as jumps made on that day were comparatively longer...the total cost of 'manufacturing' the snow was about $80, or approximately $1 per ton. This was for trucking alone as the cutting was done for free" (Hall, p.

  • Snowmaking Improvements to Be Installed at Alder Creek Adventure Center, Along Nearby Cross-Country Ski Trails During the Summer of 2019
    Date: February 23, 2019 Agenda Topic: The General Plan Committee (GPC) recommends snowmaking improvements to be installed at Alder Creek Adventure Center, along nearby cross-country ski trails during the Summer of 2019. Background: In recent years, The Tahoe region has experienced drier than average winters, forcing late opening, and/or mid-season closures. Five of the last seven seasons have been affected by low and/or no snow in areas, depriving members and guests of the opportunity to enjoy their winter amenities, resulting in a significant loss of revenue. Many Snowplay areas, Downhill Ski, and Cross-Country Ski Areas are investing in snowmaking infrastructure to ensure they can provide a quality and safe skiing surface for their customers, while also retaining skilled employees and capturing peak holiday revenue. With the overwhelming success of Tahoe Donner’s 2015 snowmaking installations along Snowbird Chairlift, the General Plan Committee voted in August of 2018, to allocate $100,000 to install necessary utilities to provide the first phase of snowmaking infrastructure along nearby terrain and Cross-Country ski trails during the Summer of 2019, see attachments. Within the approved 2019 Annual Budget and Capital Funds Projection, Tahoe Donner has earmarked $800,000 for snowmaking infrastructure and equipment at Snowplay ($100K), Downhill Ski Area ($600K), and on select Cross-Country ski trails ($100K). To obtain final construction costs and receive agency approvals by this summer, engineering drawings should commence in late February of 2019. Recommendation: Using allocated Development Funds for snowmaking improvements in 2019, Staff requests Board approval to proceed with Pure Flow Mechanics (PFM Snowmaking), for engineering of necessary snowmaking plans and documents.

  • Sun Valley Tpage.Cdr
    I. INTRODUCTION A Master Plan for the Sun Valley Ski Area was approved by the United States Forest Service in 1989. In 1991, Ecosign completed a study of the Sun Valley Resort area that included several concepts for the development of the Bald Mountain, River Run and Warm Springs base areas and expansions to the Sun Valley Village. This Mountain Master Plan update will be a logical extension of the previously completed and approved 1989 Master Plan, as well as the work completed by Ecosign in 1991. This updated Master Plan will incorporate changes in technology and market conditions that have occurred since the previous work was undertaken. Since the completion of the 1989 Master Plan, substantial lift, trail and snowmaking upgrades were undertaken by the Sun Valley Company. Furthermore, the improvements to the Warm Springs and River Run base areas (1996), have created a significant change in the distribution of skiers accessing Bald Mountain from the River Run base versus the Warm Springs base. .1 Location and Regional Context The Sun Valley Resort and associated ski facilities are located in the Smoky Mountains of south-central Idaho. The resort is located adjacent to the towns of Ketchum and Sun Valley, Idaho. Ketchum is situated on the banks of the Big Wood River. The Big Wood River flows from the Sawtooth Mountains, to the north, through the Wood Valley, and south to the Snake River. Ketchum is approximately 154 miles northeast of Boise, Idaho, 82 miles northwest of Idaho Falls, Idaho and 297 miles northwest of Salt Lake City, Utah, as illustrated in Figure 1.

Spokane And register online with CivicRec Ski & Snowboard Park General Information Meals Skiing/snowboarding can be very physical and we burn up a lot of energy, especially on those cold days. For those in the downhill programs there will be food available for purchase in the lodge. Please pack a nutritious lunch and drink. Please be sure to notify us of food allergies. The instructors will help/assist each student as necessary. We will not give money for meals. Clothing LAYERING is the best way to dress for skiing, and the concept is very simple. Articles of clothing are combined to form various strata of insulation around the body. It begins with the layers closest to the body, which trap heat and wicks away perspiration. Next comes the intermediate layers. Their job is to maintain a warm layer of trapped air. Finally, the exterior garment forms a protective membrane. This keeps wind, cold air, and water from cooling the warmth-building inner layers. The beauty of this approach to dressing is that you can add or subtract various layers to maintain the desired inner temperature. First Layer • LONG UNDERWEAR – (top and bottom) these should be polypropylene as this type of material wicks off moisture caused by perspiration. Capilene, REI brand etc. are also a desirable material.

    MAP KEY TRAIL WITH SNOWMAKING SKI TUNNEL COLORED TRAIL MARKING SYMBOLS AND LINES Skiers and riders are advised that a GREEN CIRCLE, BLUE SQUARE, BLACK DIAMOND or DOUBLE BLACK DIAMOND trail at Killington is not necessarily the same as a similarly rated trail at another resort. The trail designation system is a relative system, valid only at Killington. Skiers and riders should work their way up, beginning with the easier trails, no matter what their ability level, until they are familiar with the trails at Killington. Be aware, also, that gradients and difficulty vary within each trail. Changing snow conditions, visibility and the number of skiers and riders can also make trails more challenging. SLOW ZONES Certain areas (shown on the map by yellow dotted areas ) are designated as SLOW ZONES. Please observe posted slow zone areas by maintaining a speed no faster than the general flow of traffic. Fast and aggressive skiing is prohibited. GREAT EASTERN/GREAT NORTHERN These two trails represent Easier (Green Circle) routes that wind through several of our mountain areas. Great Eastern begins at the top of Skye Peak and ends at the base of the Skyeship Express Gondola Stage 1. Great Northern begins at the top of Killington Peak and allows skiers and riders to end their run at K-1 Lodge or at the base of Snowdon or Ramshead Mountains.
