No "expert" here but I'll give my two cents...
whether or not the elk will be there in two weeks depends on hunting pressure likely. An Elk's range can be rather large and they cycle through regions where they'll be in one area on day one and not again for several days... every 3-4 days they may cycle back through the region depending on if they are bumped from their usual routine. Likely, as soon as they hear the first gun go off close enough to matter they'll hunker down in the deepest, darkest depths of the country and stay there until its safe and they no longer hear the sound of diesel trucks cruising the logging roads and stopping to glass the same spots over and over and over. Personally, I'd do what BiggerHammer said and hunt slowly the edges of the deep, dark, dank stuff and listen close. Busting into that deep older reprod will get you a few things: tired, scratched up, pissed off, frustrated and bummed out as you just pushed elk into another area where someone was walking the logging road on the opposite side.
