I most recently visited this Stop of Interest on March 26th, 2009. It has been removed -- temporarily, i hope. I have seen it many times at an eastbound pullout on the Trans-Canada Highway (Hwy 1 / Hwy 97), 16 km east of Cache Creek, and 6 km west of the highway's intersection with Walhachin Road. All that remained of the marker at this time were the metal post supports in the ground, as shown in this photo. (50.79736, -121.10927)
