This is the map showing the horse drawn tram line which appears to end at a settlement of structures at the base of Clear Crk near the end of what is now Hudspeth Ln. You will notice that there is an interruption in the rail symbol at this point which resumes going down to connect with the SVRy mainline. If you take a look at Mal Ferrell's "Rail Sagebrush and Pine" still a great source of data after over 40 years, pg 64, you will see this tramway and short rail line described. While Alfred Mullet says the mill was a short way above Curry, this seems kinda misleading as it appears from maps that the Clear Crk mill site was a little more than 3 miles above Curry. Black Mtn. proper is farther East, so Alfred may be generalizing a bit in his geographic description.
Per RS&P George and Joseph Stoddard built the Clear Crk mill in 1892. However according to RS&P they didn't buy a locomotive until 1897. Possibly SVRy simply operated on the spur to this mill to pull out loads and deliver empty box cars.
The first Stoddard locomotive purported to have been purchased in 1897 a used 2 cyl Shay CN244 (RS&P says CN224 which is not correct)was shown on Shay builders sheets provided to me by Garrie Tufford as built for Stoddard in 1889 and makes no mention of Sunny South Lumber Co as shown in RS&P and some other rosters. This is one of many mysteries surrounding some of the associated logging engines used in the Sumpter country.
