This individual was taken by picking up a fallen, dead willow branch which had one end embedded to 5" into soil. Salamander then under this rotted end + 5" below surface. Soil moist - could be squeezed into a cast. Soil sample moisture content by drying - wet wt - 29.47%. Canopy cover ca. 80% due to overhanging willow limbs. Dense growth of polygonum 5 ft away at edge of willow cover also provides shade from late afternoon sun, so this spot is almost always shaded. Search of other logs, litter etc was not successful.
