Version 2009May17: Read the journal on the ground. The black hexstones link to Eocene. On the path to Mt. Rogers, there is a brown block on the right side that links to Precambrian. One map asks for the location of the USA 450mya, and the journal tells us that the USA and England and Sweden were at approximately the equater, so we just need to find the distance. And it tells us we can find the distance by comparing fossils from the two places... Find (at least) almost all the numbered fossils (it should still work if you just find almost all): usa fossils in Dragon's Tooth: (51 TOTAL) see the link to the map below. 1,2,3, 4,5,6,8, 13,14,15,18, 19,20,21,24,25,27,28,30,31,32,36, 38,39,40,41,42,49,50,52,53, 55,56,57,58,59,61,63,64, 65,66,69,71,72,73,74,76,77,79,80,82 england fossils(in the journal):(23 TOTAL) 3,7,10,11,12,15,19,21,24,27,32,33,42,44,50,53,57,65,68,70,77,80,81 shared between england and usa: 3,15,19,21,24,27,32,42,50,53,57,65,77,80 (14 total) using the formulas in the journal: usa-england-JC=shared/(usa+england-shared)=14/(51+23-14)=0.2333 usa-england-dist=(0.2333-0.3949)/-0.0000318=5082 Earth'sCircumference(the radius is in the journal)=2*pi*r=2*pi*6378.1=40075 usa-england-longitude=(dist/circ)*360=(5082/40075)*360=45.65 degrees click on the map that asks for the location of the USA 450mya at that location(45degrees West of England) to link to Kinnekulle!
