Bob33 is 99% correct - except Elk Area 2051 Tronsen, is open to general Eastside ML hunting (p.38 of 2009 regs, bottom section of early ML general elk seasons). GMU 251 is open for general MF (including all of Elk Area 2051); Elk Area 2051 but not the rest of GMU 251 for general ML, neither GMU 251 nor Elk Area 2051 is open for general archery.
There are a few other Elk Areas open to general season elk license holders: 3722 and 2033

for EF, 1010, 1013 and 3681 for EA, 4941 and 6061 for WA, 6064 for WM. However, most of the Elk areas are open only for special permit holders.
