Tom,
As best I can tell, Strouseville was a small settlement, platted in 1874, in Jefferson County (per DPL records). Its location seems to be to the East of Morrison, but evidently not on the Morrison branch of the DSP&P. I can't find a map that locates the place, much like "East of Eden".
It is probably long gone (or swallowed up as a suburb of Denver).
I'd hoped for extra points for illustrations, but couldn't find any. Your post suggests that your new book has a photo.
Please post a notice here when your new book is released, so I can buy it for my collection . . .
