LIDICKER 1979 June 11 cost. To the lake came M & we had some difficulty getting it back on. Then we found that the same fire wheel did not fit on the 5 wheel carts. A State Police van dropped by & found as a file what we want to exchange the bolt holes in the fire tire wheel so that we got it on. As it was cold & windy we went to the Allegiance trail on the side road (to write our (1/2 campsite level) and the we turned on its learned side. [illegible] Continued digging for nests on grid after lunch. The we went to 27 mi. S.E. of day for nests then M.x population is definitely down there, being restricted to the deep creek banks. We found them then at first on active mound. No nests were found in it's case, known. Above the creek banks, the litter is quite dry with little middle land for M.x. Brows were thick and growing nicely. Took picture of 2 ? M.S. birds just. Returned to 28 mi. (grid side) and looked for nests on N side of road. This is the area in which M.x. low abundant in 1975 & naturally common in years thereafter. Now bird sign is pretty good restricted to the small creek directly opposite the grid. Voles found here & lots of vole sign. Several nests found. Left about 1530 for drive back to Fairbanks. We brought back a total of 15 nests: 7 winter, 6 summer & winter continent, & 2 summer only.
