Perhaps you have some. Here's a selection of "then and now "photos captured over the years, standing where the photographer stood many years ago. I didn't always get it right... rushed pics, different lens, and other excuses, but hey, there was always a bike pausing nearby or idling underneath . They do, or can, cause moments of reflection. The mining community of Apex in the late 1800's, having a 4th of July parade... Apex today, a semi-ghost town about five miles NW of Central City... Bonanza, as in "It's a bonanza boys!" flared when a rich gold vein was discovered nearby. President Ulysses S. Grant visited upon reports Bonanza could be the next Leadville... The gold was mined and fires swept through the close proximity structures (A common fate of many frontier towns... wood heat, wood structures, no 911)... Tracks were laid over the Boreas Pass summit to haul ores from Leadville to Denver... The tracks were pulled up in the 1930's, and in the 1950's a road was placed on the old rail bed. Riding friend Rick cheesily agreed to place himself where the train was... The Cathedral Spires along the North Fork of the South Platte... Two rails then, two wheels today... The pastoral Dedisse Ranch above Evergreen... That pastoral Bear Creek above would turn demonic when its raging waters would crash through towns below after heavy rains. The dam creating Evergreen Lake had me off to the side for the "now" pic... The Bradford Junction community in the late 1800's would gather at this ranch for all things social... dances, celebrations, etc. Perhaps this was a July 4th gathering. Bring your best attire was often the unstated rule... Today, busy U.S. 285 passes by the same place near the town of Conifer. Had the elevated highway not be present, could have gotten lower for a better comparison... Gold Hill is the location of one of Colorado's earliest gold strikes. An image from around 1890... In a way, not a lot has changed. Well, there are more trees... less need to cut down the nearby woods for structures and heat. Colorado's oldest continuously operating school is here. The massive Four Mile wildfire of September 2010 licked the edges of the town off to the left, but a valiant firefighting effort spared the historical buildings. If you have a BBQ sandwich at the general store, a pot bellied stove is a main source of the heat and the bathroom is about the size of your coat closet... A thrilling road just for owners of new fangled cars was built above Golden around 1920... Today the Lookout Mountain road thrills for owners of two wheeled transportation devices. The sun kindly obliged and a rider was caught just in time on the far left... Marshall Pass about 70 years ago... And today... Narrow gauge trains/rails were used 100 years ago because, well, they were narrow and could squeeze between canyon walls and rivers. Denver passengers often took weekend trips into the mountains on these trains. Not far from Buffalo Creek... The aptly named Peterhead Rock today. Could have climbed higher for a more accurate "now" image, but I risked life and limb just getting this high! An 1890's hacked out road just south of Ouray... Today's famed Million Dollar Highway... Cripple Creek and Victor pumped out so much gold, the amount was greater than the California and Alaska gold rushes combined. Back then Victor had a population of 5,000... Today about 100 call Victor home... Looking west towards Westcliffe in 1900, towards the dramatic Sangre de Cristos Range... Well, someone has surely came along since then with some seeds or seedlings!
