4 valid minerals.

Detailed Mineral List:

Calcite
Formula: CaCO3
Habit: scalenohedral
Colour: white
Fluorescence: pink
Description: Translucent, doubly-terminated crystals typically <1 cm, with orange-yellow stilbite.
Reference: Harold Moritz collection
Pyrite
Formula: FeS2
Reference: Harold Moritz collection
Quartz
Formula: SiO2
Reference: Harold Moritz collection
'Stilbite subgroup'
Habit: bortyoidal to sheaf-like aggregates
Colour: orange-yellow
Description: Aggregates typically around 1 cm.
Reference: Harold Moritz collection
Zoisite ?
Formula: {Ca2}{Al3}(Si2O7)(SiO4)O(OH)
Habit: subhedral elongated prismatic
Colour: light gray
Description: Mass of elongated crystals with quartz labeled as "diopside" from this location, but looks more like zoisite but could be clinozoisite. Some edges of the specimen show rounding and weathering suggesting the original find was a glacial cobble rather than rock taken from the road cut.
Reference: Former Ed Force collection
