Before we get started with the very first Geocache of the Week: Video Edition, a quick note: the video contains spoilers with permission from the geocache creator.

Some geocaches are found easiest at night, others during the day. And some, like this week’s Geocache of the Week, are easiest at low tide (high tide would require SCUBA gear). Check out the video of geocacher Skwarepeg as she journeys into the River Thames in search of Father Thames & the Mermaid (As tides go by) (GC3KG2m).

When asked about his inspiration for this geocache, he cites his grandaughter. She likes going to London and the beach, so this location provided the opportunity to do a little bit of everything she enjoys in one day. And regarding all of the positive logs and favorite points, he said “When I get positive logs from people I don’t know or never met, I feel a tremendous satisfaction in knowing that we are all sharing a common enjoyment.”

There are many different geocaches that are easiest to find with certain conditions. What’s your favorite “condition” dependent geocache?

We all love earning smileys. Seeing that bright yellow face on your Geocaching profile page smiling back at you is the reward you get for a job well done. But how far are you willing to go for it? Would you spend days on the hunt for just one geocache? Would you commit to a 350-mile journey? If the answer is yes, then this week’s Geocache of the Week, Munich – Venice (GC1FPN1),  is for you.

The first step to finding this difficulty 2, terrain 4 geocache is to find a pair of comfortable, broken-in hiking boots. Step two is to get to the beginning stage of this multi-cache at Marienplatz in Munich. After you’re finished taking in the sights, it’s time to start putting one foot in front of the other. As you make your way through the 28 stages, you’ll have to answer questions in order to obtain the coordinates of the final stage. This may sound like a lot of work, but the stunning views along the way make the journey well worth it.

While only 36 geocachers have made the journey from Munich to Venice and earned their smiley, their logs are sure to inspire more geocachers to attempt this multi-cache. Geocacher Benjo5 said, “What an awesome experience! …Thanks for the cache, I am really happy to turn this into a smiley icon, as it was quite exceptional and challenging. And at the end, I recommend this trek to everyone. It’s really worth it. Thanks, I will not forget.”

Another geocacher who earner a smiley for this epic journey is voduska, who said, “It is difficult to express all the feelings I had and have now, but to everybody who is thinking to do this trek, I would say don‘t hesitate and go. It is such a great experience. It is extremely demanding, but extremely rewarding. And when you finally reach the beach after nearly a month and you can put down the bag and take off that terribly heavy shoes and go for a swim in the sea, you feel like … actually you feel like you’ve just crossed the Alps.”

When asked about planning and placing this geocache, DerPate said that the real planning came after he initially completed the journey. From there it was organizing all the places he had been into a great multi-cache. In regards to all of the positive feedback, DerPate said, “Even more impressive for me is the feedback of the people having done the cache: There are find logs with a length of more than 40,000 characters (almost 3 log entries are needed in average of all finds) or even more than 150 pictures were uploaded for one log.” For all geocachers aiming to earn this smiley, DerPate had one piece of advice, “To all those cachers out there: Have fun on making your own memorable experiences on your personal interpretation of such a tour :-)”

So the question is: how far are you willing to go for a find? Would you complete a 350-mile trek through the mountains? Tell us in the comments.

Normally, rocks just don’t up and move on their own. They seem to be pretty happy with sitting right where they are, not moving. But there is a place on earth where the rocks aren’t content to waste their days in the same spot. These rocks have places to go. We’re not sure where they’re going, why they’re moving or how they’re getting there. However, one thing is for sure: when you visit these rocks-on-the-go, you can find the EarthCache, The Secret of the Rolling Stones (GC2FFRV).

This difficulty 2.5, terrain 3.5 geocache and these moving stones are located in a part of California’s Death Valley National Park called the Racetrack Playa. Whether or not these stones are actually racing has yet to be determined. In fact, they’re not even all moving in the same direction. The tracks left behind the rocks move up, down and zig-zag throughout the ground. There are even some tracks that have no stones at the end of them, which has raised some interesting questions.

There are plenty of theories as to how these rocks are traveling through the landscape. Some of the rocks weigh more than 700 lbs (350kg), so the thought of a person (or even multiple people) moving these rocks is out of the question. For wind to move a rock that size, they would have to blow at over 500mph (about 800 km/h). For reference, the strongest hurricanes have had winds at around 200 mph (300km/h).  Several geocachers have offered theories in their Found It logs. “My theory is that moisture, when there is any, creates a surface that allows the stones to slide. That or aliens. One of the two.” said geocacher HOFer29. Personally, I’d hope that beings who have the technology to travel through space have better things to do than move rocks in the desert.

The most recent set of scientific theories hinges on weather factors including intense rain, ice, wind and soil composition. While nothing has been proven yet, studies continue through the use of GPS (just like us!) and sensors in the ground. The movement of these rocks is yet to be explained. Have you ever come across something you couldn’t explain while geocaching? Tell us about it in the comments.

When one ring threatened to destroy the realm, only one creature could be trusted to venture into the unknown and return it to the fiery depths of Mount Doom—a geocacher. Or at least, that’s how this version of the story goes. Create your fellowship and follow the hobbit footprints to this week’s Geocache of the Week: Helms Klamm (GC2WGRR).

Unlike the Lord of the Rings trilogy, this adventure takes place in Germany, not Middle Earth. And unlike Mordor, one can simply walk to this difficulty 1, terrain 2 geocache. The geocache creator, Caturus, modified the famous J.R.R. Tolkien storyline to fit in with a geocaching adventure. As you make your way to ground zero, feel free to take on the roles of Frodo, Sam, Legolas, Aragorn, Gimli, Boromir, or my personal favorite, Gandalf. While many geocaches are all about the journey, this geocache truly shines at the destination.

When you arrive at this geocache, don’t expect another ammo can or bison tube. You’ll be at the doorstep to a castle, complete with characters from the Lord of the Rings story (watch out for Gollum!). The castle has been found over 2,300 times and geocachers have awarded this creative geocache over 900 favorite points. The positive logs continue to roll in; geocacher Schatzfinder said, (translated from German) “Far and wide no orcs, no Nazgul or Ringwraiths. The fortress is obviously protected by magical powers that defy the dark forces of wild boars, mice and other animals. Well worth seeing!”

Geocacher Mario112 said, (translated from German) “WOW. This is something you won’t find every day. Due to all of the favorite points, we already expected something extraordinary. Our expectations were surpassed when we caught sight of Helm’s Klamm after a march through the wintry woods. Thank you for this well-designed cache, this is of course a favorite point!”

Seeing great geocache containers with amazing stories always leaves me inspired to create a spectacular geocache. What about you? If your next, or first, geocache hide will have a theme or story, what will it be? Tell us in the comments.
