If there's one thing that's notable about the Seven Pines route up Colonial Knob is that there are lot of steps on the lower slopes (nowhere near as many as the Camp Elsdon route but still). When you do the climb for the first time the steps seem to go on and on but in reality there's "only" about 200 and after climbing them numerous times they seem shorter on each ascent. But the end of the steps does not mean the end of climbing. In fact from here upwards is one of the steepest climbs around without further assistance from steps. If you're fit enough it gets you to the summit in no time though.
This cache was placed to mark the transition point where the steps end. It always seems like a convenient place for a breather so you might as well stop to find a cache while you're here. Apologies for making this a micro - something I normally try to avoid in the forest where possible.
Note that dogs are not permitted in this area. Quoting from the PCC web site:
Dogs are permitted off lead, but only in the exotic trees. Dogs are not permitted on the route up to the reservoirs which travels through native bush on the adjoining DOC scenic reserve (Colonial Knob).
