Lamberson quarry and the geology lesson: Fascinating! Karl: What highways were you on to shoot those pics? Lamberson: I have a virtual (Microsoft Train Simulator) Frisco route I've worked on off/on over the past decade or more of the Frisco circa late 1880s that goes from Monett to Talihina. You guys got me thinking about next time I revisit that project I'll extend the tail track into "Crusher Hollow" and model a quarry scene. With a name like "Crusher Hollow", it seems evident that there was at one time a rock operation in the hollow somewhere. Here's a link to the online topo service I use that should open at Lamberson: https://caltopo.com/map.html#ll=34.79536,-95.00331&z=15&b=t&o=r&n=0.25 Enjoying this thread!
