As for the other freqs you listed, none look familiar at all to me. Do you have any recordings from them, or info about what time of day you got hits on them?
Last time I was seriously logging in November, I got both in the middle of the day (1430 MT). Signal levels were so/so on both (40s-50s on a 100 scale). For comparison, I was getting 80s from Denver TRACON and 37s from A/C on the Hill City (Colby, KS) High RCAG that day.
