A small but worthwhile climbing area to check out, situated near Tumalo creek, it sits under power lines, and is fairly secluded. Most of the routes have bolted anchors at the top and can either be top-roped or led with trad gear. There is a walk around to get to the top.
Located about 15 minutes from Bend, drive out Skyliners rd, take a right onto FR 4606, and a left onto FR4609/Jack pine spring rd. There will be a small pullout on the left hand side. Walk downhill towards the water from here and you will find the cliffs.
There was a topo up on his website Revolutionclimbing.com, its gone now. It was a popular bouldering area at one point, and there is a .12 something sport line that watt's established thats apparently stellar and historic. There is at least 6 bolted lines here, maybe a few more.
If anyone wants the Shelk topo he put up and thats now down - email me firstname.lastname@example.org
I apologize CritConrad. I stand corrected. Being that the two bouldering areas, and Shevlin Park are in the same general vicinity I was under the impression that more folks know the area as "Tick Ranch", being the more "historic" name going all the way back to the 90's and all. Its what came to mind for me when I first saw "power lines" posted here.
Having the 4606 vs 4609 clarification will probably help those finding power lines versus "tick ranch".
