Elephant Mountain - interesting name for a small peak in central Washington, not too far from Yakima. For the right vehicle it might be a drive up - our rental car found the steep road to be a bit much and we hiked the rest of the way to the summit.
We climbed a little less than a mile and 500 feet to the top and then perhaps 50 yards farther east. The views once past the repeater sites are excellent and if you are thoughtful about supporting your antenna using a small shrub, you are set.
