San Juan Poniente Shaft, Ojuela Mine, Mapimi, Durango, Mexico
Cabinet, 10.0 x 6.9 x 3.9 cm
A matrix of stark contrasting gossan hosts over a dozen crystals, some doubly terminated,, of bi-pyramidal, lustrous and translucent, butterscotch-colored, wulfenite, to 1.75 cm in length. I particularly like the two crystals that have formed a wide "V." The bipyramidal form is highly developed here and the crystals large for the habit.
