DANALITE Iron Mtn., upper adit pit, Bartlett, NH 1.5 mm bipyramidal crystal in quartz.	Locality: Iron Mtn., upper adit pit, Bartlett, NH Specimen Size: 1.5 mm bipyramidal crystal in quartz. Field Collected: Tom Mortimer Catalog No.: u1010 Notes:
DANALITE Iron Mtn., upper adit pit, Bartlett, NH 4 mm field of view. Orange-red bipyramidal danalite crystals in quartz.	Locality: Iron Mtn., upper adit pit, Bartlett, NH Specimen Size: 4 mm field of view. Orange-red bipyramidal danalite crystals in quartz. Field Collected: Tom Mortimer Catalog No.: u1011 Notes:
DANALITE Iron Mtn., upper adit pit, Bartlett, NH 1.2 mm red octahedral danalite crystal with quartz.	Locality: Iron Mtn., upper adit pit, Bartlett, NH Specimen Size: 1.2 mm red octahedral danalite crystal with quartz. Field Collected: Tom Mortimer Catalog No.: u1012 Notes: These danalite crystals were found totally embedded in quartz. Breaking out undamaged crystals was very difficult. For every good one salvaged, several were broken.
DANALITE Iron Mtn., upper adit pit, Bartlett, NH 1.7 mm complex danalite crystal with quartz.	Locality: Iron Mtn., upper adit pit, Bartlett, NH Specimen Size: 1.7 mm complex danalite crystal with quartz. Field Collected: Tom Mortimer Catalog No.: u895 Notes: This danalite face appears to be a group of three intergrown crystals.
DANALITE Iron Mtn., upper adit pit, Bartlett, NH 2 mm danalite crystal in quartz.	Locality: Iron Mtn., upper adit pit, Bartlett, NH Specimen Size: 2 mm danalite crystal in quartz. Field Collected: Tom Mortimer Catalog No.: u893 Notes: Unfortunately the apex is dinged on this one.
DANALITE Iron Mtn., upper adit pit, Bartlett, NH 3 mm field of view. Pair of danalite crystals in quartz.	Locality: Iron Mtn., upper adit pit, Bartlett, NH Specimen Size: 3 mm field of view. Pair of danalite crystals in quartz. Field Collected: Tom Mortimer Catalog No.: u893 Notes: Another pair of danalite crystals on specimen u893
DANALITE Iron Mtn., upper adit pit, Bartlett, NH Field of view about 5 mm. Partially exposed yellow crystal in center may be helvite.	Locality: Iron Mtn., upper adit pit, Bartlett, NH Specimen Size: Field of view about 5 mm. Partially exposed yellow crystal in center may be helvite. Danalite forms a series with helvite and genthelvite. Encyclopedia of Minerals states danalite may be "lemon yellow." Field Collected: Tom Mortimer Catalog No.: u892 Notes: Many of the Iron Mtn. danalite crystals have a greenish-yellow helvite core. A broken crystal cross-section, lower center, shows a red rind around a glassy yellow core. An article by D. Burt, American Mineralogist vol. 65, pages 355-380, 1980, notes that at the Iron Mtn., Bartlett, New Hampshire locality, "the danalite crystals are zoned, with helvite cores and danalite rims."
DANALITE Iron Mtn., upper adit pit, Bartlett, NH Cross-section of penetration pair of zoned 2 mm danalite crystals showing a danalite red outer rind with yellow-green helvite core.	Locality: Iron Mtn., upper adit pit, Bartlett, NH Specimen Size: Cross-section of penetration pair of zoned 2 mm danalite crystals showing a danalite red outer rind with yellow-green helvite core. Field Collected: Tom Mortimer Catalog No.: u1030 Notes: A excellent example of a helvite core surrounded by a danalite rim.
DANALITE N. Sugarloaf Mtn., Bethlehem, NH 3 mm field of view	Species: DANALITE Locality: N. Sugarloaf Mtn., Bethlehem, NH Specimen Size: 3 mm field of view Field Collected: Bob Janules Catalog No.: A Bob Janules specimen Notes:
DANALITE Government Pit, Albany, NH 5.5 cm etched danalite crystal group	Species: DANALITE Locality: Government Pit, Albany, NH Specimen Size: 5.5 cm etched danalite crystal group Field Collected: ex. Dana Jewell collection Catalog No.: A Don Dallaire specimen and photo Notes:
DANALITE Government Pit, Albany, NH 1.5 cm danalite crystal group	Species: DANALITE Locality: Government Pit, Albany, NH Specimen Size: 1.5 cm danalite crystal group Field Collected: Larry White Catalog No.: A Don Dallaire specimen and photo Notes:
