Jungle exploring again

I have been taking a break from radio – at least the antenna building aspect – and other than DXing on 160 and 80m I have been playing around with other hobbies. I absolutely love exploring the jungle and looking for WW2 remnants, and since it is now the dry season, the weather is ideal for it.

Of course today it was rainy but I still went out anyway. Bringing my Nexus tablet and its GPS functionality, I can record my tracks and hike to waypoints I have made with Google Earth. This allows me to explore areas deeper in the jungle than I’ve been to before.

Today’s trip was to an area I’ve visited many times before, but this time I went further back into an area that looked promising on Google Earth. First I wanted to locate a piece of UXO (unexploded ordnance) and mark it’s position so it can be properly disposed of by the Navy’s EOD.

This is an unexploded 75mm round, probably from a Marine pack howitzer. The screw device to the left is part of the fuse mechanism.

Once I had marked the position of the UXO, I headed deeper into the jungle, into new territory for me. It did not take long to start finding stuff.

Interestingly, I did not find any other American WW2 debris around – no American bottles or anything else for that matter. Likely this was an artillery position set up quickly during the liberation of Guam in early August as the front lines pushed northwards.

Further in, I started finding Japanese bottles.

I also found a number of dug out areas in the ground. About 20ft in diameter and 4-5 feet deep, these looked to be Japanese defensive positions. They were too neat to be bomb craters, and were not dug by American bulldozers. This was probably to be a Japanese anti aircraft position.

All around these positions are scattered Japanese beer bottles.

The fact that I found only Japanese and no American bottles tells me this was a Japanese position. It is quite likely that these defensive positions were dug for 25MM anti aircraft cannon, based on the size and depth of the pits. Whether or not cannon were ever empaced here, I don’t know. I looked in some of the pits but found nothing. Due to the heavy growth, it’s difficult to see more than 10 or 15ft in any direction. I’ll definitely have to come back out here and explore some more!
