I see I never published a number of my archaeology posts from this last summer. It certainly was a busy season. I was a part of 2 excavations both on the road system. One was in June out at the head of Women's Bay while the other was out Chiniak way in July. I did do a couple of posts about the digs (click
here and
here for posts) but I barely wrote anything about the Chiniak dig and have more to add on the Women's Bay excavation. So the next few posts will be devoted to archaeology. This one will focus on what we found out at Chiniak.
The Chiniak dig was an impromptu excavation. Road construction crews uncovered archaeological deposits and we were called in to learn what we could before it was destroyed by road construction. A great opportunity to learn something! The site had 2 components - a late prehistoric (circa 500 year old) hunting and fishing 'processing' camp, and a far older (maybe 4500 BP?) 'special purpose' site. We found very little at the latter and we are wondering if perhaps they were processing plants or quarrying sods for a nearby village. It certainly was fun to dig in bright 'High Vis' clothing!
The deposits were deeply buried under sand blown up from the beach. Digging down we'd find deep layers of practically pure sand interspersed with thin layers of rotted organics that created a dark soil. We realized that the dark layers represented periods of time when the sand stopped blowing and vegetation grew on top of the site. People seemed to have occupied the site near the end of the stable periods.
Right now the locality is stable with a thick mantle of vegetation and no blowing sand. But we realized that prior to the 1964 earthquake there was a big sandy beach in front of the locality. In 1964 the land sank and the beach eroded away - no more sand. It looks like this has happened on a regular basis through time. Every 500 years or so there is an earthquake, the coastline erodes, and for maybe for a 100 years no blowing sand and there is sod development. Then with uplift the beach gets re created and more blowing sand.
Pretty cool story - more on the artifacts and fauna in post to come.
