Amid the trees that cover more than half of the 6 square miles that make up Camp Bonneville, one might find Hunter Decker carefully tying a pink ribbon to the trunk of a Douglas fir.He’s marking boundaries within “thinning units” — where they’re removing trees to make room for the healthier trees to grow. And it’s also the season for identifying lumber for transmission poles: those tall columns of wood that support power lines.“Timber cruisers” were out on Camp Bonneville grounds on a recent sunny Wednesday morning, looking for ideal trees for future utility poles. Part of Decker’s job, in addition to permitting, is to set up timber sale auctions for Clark County.“We’re thinning the transmission pole trees right now. So, like the ones you see on the side of the road with the power lines — that’s what they’re keying into and we’re selling. They’re going to mark the trees to remove them, then I’ll come give my blessings,” Decker said.Steve Knight has been “cruising” for 20 years and was out looking for ideal timber with a newbie, Melynn Vandehey. They work with McFarland Cascade Holdings Inc., which has corporate headquarters in Tacoma.
