| Species: SCHEELITE Locality: Holts Ledge Scheelite Prospect, Lyme, NH Specimen Size: 5 cm specimen of massive scheelite, natural light and short wave UV illumination. History: Purchased from Ron Kendig (Nature's Window), ex Dennis Gross, Bryant Pond, ME Catalog No.: TBC Notes: Phillip Morrill lists a scheelite and powellite prospect "between ski tow and next trail." of the long-standing Dartmouth College ski area, Lyme, NH. Myself and others have searched for this spot without success. The "Dartmouth Skyway" is one of the oldest ski areas in the northeast...the training area for the Dartmouth ski team. I am convinced the trails and lifts have been substantially modified since Morrill's time....Morrill's "tow and trail" reference is no longer valid. The "Skyway" is still an active ski area, with a nice new lodge. This is the only Holts Ledge scheelite specimen I have ever seen, as well as the largest known scheelite from New Hampshire. Although many specimens may have been collected from this locality decades ago, the non-descript daylight appearance makes it probable that many of these specimens were discarded by those who may have inherited such specimens. |
| Species: GRAPHITE - crystals in quartz Locality: Beebe River ledge, east bank below falls, Campton, NH Specimen Size: 4 cm specimen of micro graphite crystals to 2 mm in quartz. Field Collected: Tom Mortimer Catalog No.: TBC Notes: These were collected from a weathering sulfide vein exposed on a near vertical, 40 plus foot high, ledge rising from east bank of Beebe River. Initially I thought the lustrous black flakes were simply biotite. On closer examination, molybdenite, hematite, and graphite all seemed to be possible ID's. When examined by John Jaszczak in June 2012, graphite or molybdenite seemed most likely. A Raman spectroscopy analysis by John in late July showed these shiny black crystals to be graphite. This east bank area of the Beebe River is only accessable from the west side when the water level is low. August is best. Other minerals present in this weathering sulfide vein include pyrite, gypsum, halotrichite, and actinolite. |
| Species: FERRIMOLYBDITE Locality: Holts Ledge, Lyme, NH Specimen Size: 3.5 cm specimen with yellow ferrimolybdite crust and molybdenite crystals in iron-stained, granular, quartz. Field Collected: Tom Mortimer (1988) Catalog No.: 765 Notes: |
| Species: FERRIMOLYBDITE Locality: Holts Ledge, Lyme, NH Specimen Size: 6 mm molybdenite crystal with pale-yellow ferrimolybdite coating in iron-stained, granular, quartz. Field Collected: Tom Mortimer (1988) Catalog No.: 661 Notes: |
| Species: PYRITE Locality: Holts Ledge, Lyme, NH Specimen Size: 1.5 cm pyrite crystal in granular quartz. 3.7 cm over-all specimen size. Field Collected: Tom Mortimer (2004) Catalog No.: 1401 Notes: These pyrite crystals are undergoing alteration to limonite. |
| Species: PYRITE Locality: Holts Ledge, Lyme, NH Specimen Size: 2.1 cm pyrite crystal in granular quartz. 4 cm over-all specimen size. Field Collected: Tom Mortimer (2001) Catalog No.: 1227 Notes: These pyrite crystals are undergoing alteration to limonite. |
| Species: POWELLITE pseudomorph after molybdenite Locality: Holts Ledge, Lyme, NH Specimen Size: 6 mm Powellite pseudomorph after molybdenite in natural light and short wave UV illumination. Field Collected: Tom Mortimer Catalog No.: 1400 Notes: Powellite is a fluorescent mineral. |

| Species: SCHORL Locality: Playter Mine, Springfield, NH Specimen Size: 2.6 cm specimen. Field Collected: Bob Wilken (2010) Catalog No.: Notes: |
