04 Feb 06:  0900 - 1600, Medicine Bow National Forest.  Helped instruct
a level-1 avalanche field  session at the Ladies Downhill on Libby Creek
Trail.  Practiced beacon searches, snowpit evaluation,  and rescue
scenarios.  Results of a test pit dug on a SE-facing slope (35-40
degrees) were as  follows:

110 cm   -------------- Snow surface --------------------------------
                        F
 90 cm   -------------- Easy Q1 shovel shear ------------------------
                        several 2-cm layers of hardness P
                        interspersed with 2-cm layers of hardness 4F
 70 cm   ------------------------------------------------------------
                        4F at top, grading to 1F
 20 cm   -------------- Easy Q1 shovel shear ------------------------
                        1F, faceted crystals
 10 cm   ------------------------------------------------------------
                        K, refrozen depth hoar
Ground   -------------------------------------------------------------

Two Rutschblocks failed at the uppermost easy shear layer, one with
score 3, the other with score 4.
