Where the heck is Poncha Springs, Colorado??

Here's a map showing the Upper Arkansas Valley. From Denver, we drive up Highway 285, past Bailey, over Kenosha Pass, and through South Park (for which the famous "adult" cartoon show is named). We cross the Arkansas River at Johnson Village and turn left towards Salida. From there, we track the shimmering Arkansas on the left and the majestic Collegiate Peaks on the right until we reach Highway 50. A left turn puts us in the little town of Poncha Springs (official population - 474). We take another quick left onto 50 towards Salida (a mere 3 miles down the road). A half-mile down 50 takes us to Poncha Springs Lane where we turn right and then a couple of hundred meters and it's a left turn onto East Ouray. Our address is 1133 E. Ouray at the very east end of Little River Ranch.
