Noah has been bugging us to take him to the Ape Cave Mount St. Helens National Volcanic Monument for a LONG time. We finally made it up there today. It was amazing. It took us a little over an hour to drive up to the park, from there it's a quick walk to the entrance of the lava tube and spelunking we went! The old lava tube was larger than we expected, very dark and very chilly. It was a constant 42 degrees with a slight breeze. Luckily we didn't go during the rainy season so the drops of water only landed on us occasionally. It was tough getting good pictures in the cave, I needed to use the auto focus because I couldn't see far enough to manually focus the camera. The camera had a tough time too! I still managed to take a ton of pictures, so many that I decided to go with a slide show this time. This was a fun experience and I would highly recommend you go and experience the Ape Cave for yourself. However, we did decide against navigating the upper portion of the cave, we were worried about Oliver making his way through/up/over the various breakdown piles. The upper portion is a bit more technical than the lower portion. He did GREAT in the lower portion though. We did hike on the outside trail up to the far end of the upper cave and made our descent into the cave up there.
