Rock cuts in the vicinity of the current Interchange 10 were blasted for the redevelopment of the former Route 6A bypass into Interstate 84 circa 1960. Most minerals are present as lower temperature phases in small Alpine clefts in the gneiss, such as albite, anatase, apophyllite, calcite, chabazite-Ca (nice orange-yellow rhombs), chlorite, heulandite-Ca, laumontite, muscovite, natrolite, prehnite, pyrite (tiny cubes), rutile (reticulated needles) and, most abundantly, stilbite subgroup.
