$USGT The nappe shape shown in cross section is based on down-plunge projection from this and adjacent mapped areas. Locally, units of Devonian to Cambrian age are inverted and structurally disrupted above the nappe on the northwest flank of the range east of Snell Creek. They may be part of the higher west-facing Soldier Creek nappe that is mapped northeast of this quadrangle by Howard (1966, 1980), Snoke (1980), and MacCready and others (1997). The opposite vergences of the Lamoille Canyon and Soldier Peak nappes exemplify an extraordinary variety in foldnappe facing directions in the Ruby Mountains (Howard and others, 1979; Howard, 1980).
