Clinging to the flanks of Eldorado Mountain and turning thru the 10 degree curve inside Tunnel 16... This westbound Union Pacific manifest heavy in frack sand blasts out of #16 as it continues into one of toughest stretches of the modern "Moffat Road". Virtually untouched since the railroad was built, this section of the Moffat Road makes you feel like you are truly in Wilderness, despite the fact that the sprawling Denver Metro is on the other side of Eldorado Mountain.
