Bradgate Park, we're back investigating ~14,000 year old archaeology

Least Cost Pathway (LCP), the path between two locations that costs the least to traverse, where cost is a function of time, distance, or some other criteria defined by the user.

This section explores the routes our hunter gatherers might have used (figures 1 & 2).
- Least Cost Pathway - hypothesis how hunter gatherers could take advantage of migrating ungulates. The Wyoming mule deer migration parallel.
- Least Cost Pathways between the four LUP sites in the East Midlands & from Grime's Graves used as a reference point because of its source of flint & closeness to the land bridge of Doggerland. An overlay of the landscape 11,000 BP can be toggled on/off. The white icons are sites within the vicinity with either possible or confirmed LUP finds.
- Least Cost Pathways from European LUP sites to the UK across Doggerland using General Bathymetric Chart of the Oceans 2014, 30 arc-second grid.
- 3D view of pathways between Europe & UK based on the General Bathymetric Chart of the Oceans; elevations x 200. Use mouse controls to manoeuvre & the controls top right to set the flood plane at -32 (easier done by typing in the number). It is apparent that with rising sea levels, the northern route would be more important by 9,000 BP.
Frachetti et al 2017 report an additional technique for simulating the optimal pathways of migrating herds at 750 m to 4,000 m elevation by using remote satellite images & the normalised vegetation index.
