Detailed Mineral List:

Almandine ?
Formula: Fe2+3Al2(SiO4)3
Habit: crude dodecahedral
Colour: very dark red/black
Fluorescence: none
Description: From my personal mineral experience and my specimens from this site, the garnets appear to be almandine. Small crystals are considered rare and a lucky find, so these large crystals (up to over 1") are probably the best from the locale.
Beryl
Formula: Be3Al2(Si6O18)
Beryl var. Aquamarine
Formula: Be3Al2Si6O18
'Garnet Group'
Formula: X3Z2(SiO4)3
Microcline
Formula: K(AlSi3O8)
Muscovite
Formula: KAl2(AlSi3O10)(OH)2
'Plagioclase'
Formula: (Na,Ca)[(Si,Al)AlSi2]O8
Quartz
Formula: SiO2
Quartz var. Smoky Quartz
Formula: SiO2
