Cameron Park Adventure: Through the Gateway Multi-Cache

Hello Traveler. I will try to be brief. I am unable to locate a place of great importance and seek your assisstance. Read on if you can lend a hand.

There is a gateway; a very old gateway. It once served an important role but has long since fallen into disrepair. Well... that's what I've heard at least. I've never actually seen it. Few have. One of those men, an individual whom I never had the pleasure of meeting, left behind serveral markers that reveal the path through the Gateway. Yet at the same time, the way has been obscured. I was once able to locate the initial marker but couldn't decipher the codes within. I've indicated the location of that first marker on the map. Perhaps your witts will serve you better than mine did.
