I discovered some bones along the bank of the creek where the water washes away the dirt every winter. Within a couple more years, they will completely vanish. Kinda sad. I am not sure if I should report my discovery or just let it rest in peace since Im pretty sure it is ancient and not a modern... well, death. Im more of the mind to let it be. I would be pretty ticked if someone dug up my grandmother. I also finish the stone tool arrow shafting. They are getting closer to completion. This is taking some time!

- Adventure Hunt at Cougar Ridge, pt 17. Bob, Tom and Making Arrow Shafts Checking the trail camera. Collected 4 ocean spray/arrow wood shafts on the way in. Checked the camera on the knob below the cave first. Got LOTS of pictures of squirrels, birds, chipmunks, and a nice closeup of a bobcat. Beautiful! Up at the cave I got one pic which ended up being the cougar. He's still hanging around even with the warmer weather and still showing up around daylight. Hmmm, I think Im finally finding a pattern. I started on some arrow shafts for hunting using only stone and bone tools I collected and made. The shafts were collected simply by pulling them off. I cut them extra long with my basalt saw. I cut them long because they almost always split a little at the very ends whild drying. I then scraped them down with the jasper scraper then sized them by continuing to scrape and checking the diameter with the bone sizing tool. Once sized, I run them over the heat of the fire to sear the outside so they wont split while drying which ocean spray is notorious for. It must sear the outside or something like that. Im not sure what it does but it does work very well to prevent splitting and checking. They are then bundled up and tied so they will dry strait. I use a length of stinging nettle cordage I made. I'll take them out and straiten them every week or so till they are dry.

Solfataric activities (cracks where steam, gas, and lava are emitted) were last observed at the summit in 1912, but no other documented events had taken place until an eruption in the early hours of 29 August 2010.

- Mount St. Helens- Google Earth. Mount St. Helens is an active stratovolcano located in Skamania County, Washington, in the Pacific Northwest region of the United States. It is 96 miles (154 km) south of Seattle and 50 miles (80 km) northeast of Portland, Oregon. Mount St. Helens takes its English name from the British diplomat Lord St Helens, a friend of explorer George Vancouver who made a survey of the area in the late 18th century. The volcano is located in the Cascade Range and is part of the Cascade Volcanic Arc, a segment of the Pacific Ring of Fire that includes over 160 active volcanoes. This volcano is well known for its ash explosions and pyroclastic flows. Mount St. Helens is most famous for its catastrophic eruption on May 18, 1980, at 8:32 am PDT which was the deadliest and most economically destructive volcanic event in the history of the United States. Fifty-seven people were killed; 250 homes, 47 bridges, 15 miles (24 km) of railways, and 185 miles (298 km) of highway were destroyed. A massive debris avalanche caused an eruption, reducing the elevation of the mountain's summit from 9677 ft (2950 m) to 8365 ft (2550 m) and replacing it with a 1 mile (1.6 km) wide horseshoe-shaped crater. The debris avalanche was up to 0.7 cubic miles (2.9 km3) in volume. The Mount St. Helens National Volcanic Monument was created to preserve the volcano and allow for its aftermath to be scientifically studied. As with most other volcanoes in the Cascade Range, Mount St. Helens is a large eruptive ...
