L'Obex 1979 June 11 cont. In the process of collecting the roots for a journalist in Anchorage (Glen Haas), while digging my plot I found systems of burned burrows empty with cache cavities. Burned systems are very complex, it difficult to distinguish the structure of root systems at first glance, though they go down to penetrate well into this zone is about 1 ft. below surface of litter. Burrows of cache cavities seem open to be located in junction zone where litter (mostly moss) meets the soil, and a gap is easily formed. Large cavities, now mostly completely empty, were often found under the shallower parts of a dead spruce which may be partially filled over or laying on the ground. Or a few years, nothing remains of a winter cache if horizons were found. A good place to look is where moss has grown up on a tangled mass of deadened branches and roots. Two cache cavities were about 6" high but with a diameter of at least a meter and had several funnel burrows coming into them. No winter root was found in these caves, so it has not possible to tell how many nests related to hiddens. Summer nests were of dry grass, and often shallower or even on top of winter nests. Some were open on top like a bird's nest and others were covered. One that I found was in a side branch about 6" off of a large empty cavity at the same depth. We wound back: Fairbanks about 1815.
