Gallery of log for Thornleigh Quarry & Zig Zag Railway - Historic Engineering Marker #88
Very cool. We were here grabbing GC caches to preposition us for our 7000th find, so weren't actually looking much towards GCA (we were on a very tight schedule!). We did the EC here and needed a photo with the Engineering Marker - what?! Very cool....
