1) Name and location of potential project:
The Crump Geyser area is located in Warner Valley, Lake County, near the hamlet of Adel, which is 53 km east of Lakeview, Oregon, on Highway 140, and 287 km northwest from Winnemucca, Nevada. The Crump Geyser area is located within the moderate to high thermal activity zone, which extends from Washington State and covers much of central and eastern Oregon.

Two geothermal zones have been documented in the Warner Valley near Adel. The Southern Geothermal Zone is located just north of Adel. This zone follows an extensive, north-trending and elongate mound of calcareous tufa with numerous hot springs, seepages and warm water marshes. The zone is structurally controlled and located along, and immediately east of, a complex system of faults, which define the prominent western scarp of Warner Valley. The recorded temperatures in these springs are in the 38-56o C range. The water temperature of the older, original Crump Geyser reaches a maximum 122o C below 10 m depth.

The Northern Geothermal Zone is located along the northwestern shore of Crump Lake. This zone is characterized by hot springs and seepages, which originate along the base of a complicated, segmented, NW-trending fault system. The springs in this portion of the valley appear to have a larger component of meteoric water, higher flow, nd lower temperature readings, which are in the 24-30o range.

2) Type of project:
Electric Power Plant

3) Status and history of project:
The Crump Geyser formed as a result of a well drilled by Nevada Thermal Power Company. In the 1950's, the company conducted a systematic drilling program in this part of Oregon, Nevada, and California, in a search for a source of natural superheated steam. Nevada Thermal Power Company (NTPC) was a division of Magma Power Company of California.

Two days after the completion of the hole, the well erupted sending a continuous column of steam and hot water to about 45 m in the air. It was, at this time, the site of the largest continuously erupting geyser in the United States. The geyser was vandalized in the early 1960's. Several boulders were thrown in the casing, after which the behavior of he geyser changed. It continued erupting, but only to a height of approximately 18 m, and with periods of inactivity of about 2 minutes. The geyser has been continuously active for several years.

Waters from several springs were sampled for geochemistry. The geothermometers calculated from the geochemistry suggest a source water temperature of at least 170o C. There may be hotter water supplying this 170o C reservoir.

In August 2005, NGP reported that they have acquired geothermal leases on 6500 acres of private land covering the "Crump Geyser" and an extensive hot spring system in southern, Oregon. NGP has free access on the surface for exploration and development and the right to lease land required for the plant site, production well field, pipelines and transmission line right of ways.

As of May 2007, this project is currently in the process of securing a power purchase agreement (PPA) and final permits.

10) Other information of interest:
The Renewable Northwest Project considers the Basin and Range country of southeastern Oregon one of the most promising geothermal areas in the Pacific Northwest.

In the mid 1980's the site was visited and evaluated by Gordon Bloomquist, as part of the major, four state assessments for Bonneville Power Administration (BPA). The geyser ranked as one of the better among over 1100 sites assessed (Bloomquist, 2005). The power generating potential of the site was estimated to be 85 MW.
