Long Valley (Happy Jack) Ranger <br />station which is located approximately 64 km south of Flag- <br />staff. The site was in a large clearing, formerly a lumber <br />camp, near the crest of the Mogollon Rim. Commercial power <br />was available and concrete pads existed which were used for <br />siting equipment. <br /> <br />All equipment at the Happy Jack location was operated <br />by a crew of two people at the site. Housing for one NAWC <br />employee was provided in U.S.F.S. housing which was available <br />on a temporary basis. The second person was a resident Forest <br />Service employee whose services were obtained on a part-time <br />basis. <br /> <br />The third site, near the town of Camp Verde, housed equipment <br />and NAWC personnel which were used to obtain soundings of <br />the atmosphere using a rawinsonde system. Balloon-borne instrument <br />packages (radiosondes) were released and tracked throughout <br />their ascent to provide vertical profiles of temperature, <br />moisture, pressure and winds. The tracking and recording <br />equipment was contained in a small trailer, while balloon <br />inflation and supply storage facilities were provided through <br />rental of space in a local aircraft hangar. Personnel operating <br />the equipment were housed in a travel trailer adjacent to <br />the equipment unit. <br /> <br />In addition, precipitation gauges were deployed at Happy <br />Jack and six other locations as indicated on Figure 2.1. <br />Site names, gauge locations and elevations are detailed in <br />Table 2-1. These stations provided data concerning the timing <br />and distribution of snowfall over the general area and were <br /> <br />2-8 <br />
