Hey John and S.P,
The drawing of the Tell Tale wasn't in MR -- it was in Bob Brown's old
Slim Gauge News, predecessor of the
Gazette. If you'd like a copy, contact me off line, and I'll send it as a PDF.
The stone warehouse was built by the Greens as additional storage for their large stone store; I suspect bulk items were stored there, like bagged flour and beans, building materials, paint, etc.
http://digital.denverlibrary.org/cdm/singleitem/collection/p15330coll22/id/78093/rec/483The stock pens were on one of two spurs, at the end of the long spur running past the stone warehouse. They are visible in the c1910 McClure photo above, and were present at abandonment. The Klingers' book has several photos in which they can be seen. So, yes, they saw seasonal activity with stock shipments over the years.
As to the roads, S.P., the road leading to the left of the bridge is likely an improvement to connect the road to Pine Grove (lower left frame) with the wagon road that paralleled the railroad east toward Riverview and Dome Rock:

I may be imagining things when I pointed out the "switch stand" in the 2nd photo in my post above, with the South Platte bridge -- the Buffalo siding was removed sometime in the 1930s. Perhaps the new road connection followed the grade of the siding until it intersecting the much older wagon road.
The road disappearing in the distance is today known as South Buffalo Creek road. I think it ran up to serve a shingle mill. At least current maps refer to a "Shingle Mill Creek", a tributary of Buffalo Creek, near where the road ends.
