Monte Creek to Pritchard, Phase 1

Map from Ministry of Transportation and Infrastructure Website

  • This section of the Trans-Canada Highway 1 (TCH1) completed 2012
  • Archaeological Site 25, located at Miner’s Bluff was a heavily used site over thousands of years. 1000’s of artifacts were found here as well as 100’s of tools
  • Site 25 is considered one of the premiere tool making sites in North America due to the high density of tools, artifacts and lithic scatter (leftover flakes from tool making)

Update to Pritchard to Hoffman’s Bluff (Phase 1) Archaeological Site

During construction on August 16, 2013 there was a significant archaeological discovery, all work stopped in the area and shortly after, a larger team of archaeologists and monitors began a more intense study of the area. Three radiocarbon dates taken from samples are among the oldest dated archaeological sites on the Interior Plateau:

  • EeQw-102-04; black bear foot bone: BP (Before Present) 7,970 to 7,840
  • EeQw-102-22; hearth charcoal: BP 8,160 to 8,090 and 8,060 to 7,960
  • EeQw-102-23; charcoal below hearth: BP 8,770 to 8,540

Two habitation dates have been identified. The younger one is dated to around 7,000 BP and contains stone artifacts, animal remains and a hearth or campfire. The older habitation contains animal bone, stone flakes and dates to 7,800 BP and seems to be related to an ancient stream bed. This arch site can provide a rare opportunity to tell about a little understood period of time in the early habitation of the region. This campsite was thoroughly documented.

According to numerous oral history and stories, this area was a well-used campsite for Secwepemc travelling west to S’tkemlups.


Pritchard to Hoffman’s Bluff, Phase 2

  • Phase 2, four-laning a 3.1km section, includes the Bluff section
  • Construction starting in 2015
  • Award Contract January 2015
  • Completion Fall 2016

Rat Cave

Through the consultation process with the Lakes Division bands, the Ministry has been aware of the sensitivity of the Rat Cave. In respect of this, the Ministry directed the project’s geotechnical engineering consultant, EBA Engineering, to conduct a field assessment of the area and prepare a report with recommendations that would ensure the cave is not damaged by the highway construction work. Here are some of the key aspects of the report:

  • The edge of the Rat Cave is 73 m away from the project right of way. The first large rock excavation area that will require blasting is approximately 100 m away (300 ft).
  • There are cracks in all of the rock in this area. The talus slope (pile of broken rock) below the cave is an indication that pieces of rock have been breaking away and falling down this slope in the past and will continue to do so regardless of the highway construction.
  • Vibrations from blasting is measured in mm per second. For protection of the Rat Cave the report is recommending a maximum of 13 mm/sec. This number is what would normally be allowed where blasting was occurring immediately beside a building. With the main rock excavation area 100 m away, this is a very safe/conservative allowable vibration number
  • The 13 mm/sec allowable vibration will be monitored using a seismograph

The recommendations from the report were included in construction contract that Emil Anderson Construction (EAC) has signed and are a requirement for them to follow. EAC has committed to working within these requirements and has taken a couple of Neskonlith staff members out to the site to show them where the rock blasting will occur and what safety precautions are being taken.

As of May 2015, several community meetings were held to address the concerns of Community Members:

  • May 1, 2015 Sacred Site Meeting, with Grandmothers and Elders representative of the STS Bands
  • May 8, 2015 Rat Cave Site Walk Through, with Elders and Leader representatives of the STS Bands, and Ministry of Transportation and Infrastructure Engineer and Project Manager
  • May 21, 2015 Rat Cave Site Walk Through, with Elders, Leaders and Band Member representatives of the STS Bands, and Ministry of Transportation and Infrastructure Engineer, Project Manager, Archaeologist, Blast Specialist, and Rock Specialist

  • Eagle River has long been an important travel route by canoe, food fishery, food and medicinal plant gathering, and hunting area for Secwepemc for thousands of years
  • As MoTI will be 4 laning the bridge, STS is working on several strategies to ensure aquatic and ethno botanical habitat is protected
  • This Direct Award Contract is being undertaken by Splatsin (Spallumcheen of the Secwepemc), who have direct cultural and economic ties to this area
  • Splatsin is also developing a Sexqéltkemc Fishery Legacy Project for this section, which includes:
  • A STS Traditional Fish Site, with camping, parking and a cultural interpretive kiosk
