#9135 - Vegetation Mastication at La Pine State Park

The Inadvertent Discovery Plan (IDP) should be followed if cultural materials, including human remains are encountered during clearing or trail maintenance activities.

Protocol for Coordination in the Event of Inadvertent Discovery

· In the event of an inadvertent discovery of cultural materials, including human remains, all work will stop immediately in the vicinity of the find. A 30-meter buffer should be placed around the discovery with work being able to proceed outside of this buffered area, unless additional cultural materials are encountered. The archaeological remains will not be touched, moved, or further disturbed. Field staff/contractors must immediately contact the OPRD Park Manager, OPRD Archaeologist, and OPRD Forester for guidance.

· The area must be secured and protected to avoid further disturbance. Methods to secure and protect the area include marking the protected area boundary with flagging, clearing stakes, traffic cones, or other similar methods. In some instances, OPRD-designated personnel may need to monitor the area until direction is given by the OPRD Archaeologist.

· The OPRD Park Manager, OPRD Archaeologist, and OPRD Forester will be notified. The OPRD Archaeologist will notify the State Historic Preservation Office (SHPO) and appropriate Tribes. If possible human remains are encountered, the OPRD Archaeologist will contact the Oregon State Police, Legislative Commission on Indian Services (LCIS), SHPO, and appropriate Tribes.

· Oregon State Police: Craig Heuberger 503-731-4717, cell 503-508-0779

· LCIS: Patrick Flannagan 503-986-1067

· Appropriate Tribes: As designated by LCIS

· SHPO: John Pouley 503-480-9164

· Work will not resume until OPRD Archaeology staff are on-site and able to assess the situation in consultation with the SHPO and affected Tribes.

· If human remains are encountered, do not disturb them in any way. Do not call 911. Do not speak with the media. Secure the location. Do not take Photos. The location should be secured and work will not resume in the area of discovery until all parties involved agree upon a course of action.

· The OPRD Archaeologist will consult with SHPO and appropriate Tribal Governments to determine an appropriate course of action.

· Archaeological excavations may be required. This is handled on a case by case basis by the professional archaeologist, working closely with the Park Manager and/or OPRD Forester, in consultation with SHPO and the appropriate Tribes.

When to Stop Work

Tree thinning and/or brush removal work may uncover previously unidentified Native American or historic period artifacts. Work must stop when the following types of artifacts and/or features are encountered:

Native American artifacts may include (but are not limited to):

· Flaked stone tools (arrowheads, knives scrapers etc.);

· Waste flakes that resulted from the construction of flaked stone tools;

· Ground stone tools like mortars and pestles;

· Layers (strata) of discolored earth resulting from fire hearths. May be black, red or mottled brown and often contain discolored cracked rocks or dark soil with broken shell;

· Shell lenses; shell midden

· Structural remains- wooden beams, post holes, fish weirs;

· Human remains

Euro-American artifacts may include (but are not limited to):

· Glass (from bottles, vessels, windows etc.);

· Ceramic (from dinnerware, vessels etc.);

· Metal (nails, drink/food cans, tobacco tins, industrial parts etc.);

· Building materials (bricks, shingles etc.);

· Building remains (foundations, architectural components etc.);

· Old Wooden Posts, pilings, or planks (these may be encountered above or below water);

· Remains of ships or sea-going vessels, marine hardware etc.;

· Old farm equipment may indicate historic resources in the area.

· Even what looks to be old garbage could very well be an important archaeological resource;

When in doubt, call it in!

Proceeding with Debris Treatment

· Debris treatment can proceed only after the proper archaeological inspections have occurred and environmental clearances are obtained. This requires close coordination with SHPO and the Tribes.

· After an inadvertent discovery, some areas may be specified for close monitoring or ‘no work zones.’ Any such areas will be identified by the OPRD Archaeologist and shown to the Park Manager, OPRD Forester, and Contractor.

· In coordination with the OPRD Archaeologist, the OPRD Park Manager and/or OPRD Forester will verify these identified areas and be sure that the areas are clearly demarcated in the field, as needed.
