FROST PENETRATION AND TRAFFICABILITY IN TWO PEATS AS AFFECTED BY SNOWPACK AND SURFACE MOSSES

UNFROZEN PEAT SOILS ARE NON-TRAFFICABLE FOR HEAVY VEHICULAR TRAFFIC UNLESS THEY ARE FROZEN, A FACT WHICH IMPEDES LOGGING ACTIVITIES IN THE GREAT LAKES STATES. TWO SWAMPS WERE SELECTED FOR EXPERIMENTS UNDER VARIOUS CONDITIONS OF FREEZING AND THAWING. ONE WAS A SHALLOW FORESTED WOODY PEAT 1 TO 2 FEET DEEP, THE OTHER, A FORESTED SPAGHNUM MOSS PEAT 6 TO 8 FEET DEEP. INSTRUMENTS WERE SET IN AREAS WHERE THE SNOW WAS UNDISTURBED, WHERE THE SNOW WAS PACKED BY TRAMPLING AFTER EACH FALL, AND WHERE THE SNOW WAS CLEARED ALL WINTER LONG BY SHOVELLING. THE RESULTS OF THE TESTS WERE GIVEN AND COMPARISONS WERE MADE.
