This is one of 81 puzzle caches created and hidden along the Medicine Bow Rail Trail. Each of the 81 caches has a unique Difficulty/Terrain combination ranging from D1/T1 through D5/T5; hence, putting all 81 jig saw puzzles together and then finding the caches along the rail trail allows you to fill a complete Fizzy Matrix.
Medicine Bow Rail Trail
The rail trail spans a 21-mile section of the original Laramie, Hahn’s Peak and Pacific Railroad which was constructed between 1901 and 1911 and traversed from Laramie, Wyoming to Coalmont, Colorado. The railroad operated for more than 90 years and was the highest elevation standard gauge railroad in the US (the higher portions spanning between 8,770 and 9,030 feet elevation). Trains ran daily to haul minerals, livestock, coal, and lumber between North Park and Laramie. The rail line was abandoned in 1996 and in 1999 the rails and ties were removed.
The rail trail was constructed over the 21-mile stretch of the old rail bed during the period 2005 to 2007. The trail is accessed via six trailheads; mile markers (showing the original railroad mileage from the northern terminus of the railroad near Laramie) are installed at each mile. It has a hard-packed gravel surface, averaging 10 feet in width. The trail is used for hiking, mountain biking, horseback riding, snowshoeing, and skiing. At the time the 81 caches were hidden, recreational trail use was found to be light. ATVs, snowmobiles, and other motorized vehicles are prohibited. Dogs are allowed if they are under voice control. As a general rule, bikes should not be used until after snow has melted and the trail has dried out--about mid-June.
The Geocache
Click on the highlighted link below the photo to bring up the jig saw puzzle that must be completed in order to obtain the coordinates for this cache. After the final piece is placed, a completion message will appear that gives the location as well as a specific hint. As a general rule, D1 puzzles have between 75 and 125 puzzle pieces; D2 puzzles have between 125 and 175 pieces.....on up to D5 puzzles that generally range between 475 and 525 pieces. Caches rated T1 are handicap-accessible. Certain T5 caches require easy tree climbs.
The theme for the 81 caches is “Geocaching Around the World”. Denali50 and I took most of the photos during past trips across the US as well as on many trips to various countries around the world. Others were taken on my past mountain climbing trips. Generally, the GC identifier and name of an actual cache that is reasonably near to the location where the photo was taken, is provided at the end of the text. Because most of our international trips were for finding birds and climbing mountains in years that preceded the advent of geocaching, it is rare that we have actually found the featured cache! Oh, how I wish... But the chosen geocaches are included for your pleasure, should you care to look at them.

January Sunset on Pleneau Bay, Antarctica
https://www.jigidi.com/created.php?id=A644IDQ2
We passed through the picturesque Lemaire Channel along the west side of the Antarctic Peninsula and came on an incredible natural display of Pleneau Bay's icebergs, sea ice and fresh water ice (with their attendant Leopard, Crabeater, and Weddell seals and abundant penguins). After a 3-hour Zodiac tour amongst the ice and wildlife we returned to the ship just in time to witness this gorgeous sunset!
Enjoy putting the jig saw puzzle together and then your time afield along the rail trail!

See GC3A8JC and read the description for the EarthCache Ice, Ice and More Ice. The cache is right in Pleneau Bay!
