Figure 32. Equal area net plot of the poles to joints within rocks of the Black Stuart Group,
and Guyet, Waverly and Greenberry formations of the Cariboo Terrane. A, B and C are averaged
plots from domains 2, 3 and 4 (Fig. 25) with 67, 93 and 85 points respectively.

Stuart deformation and peneplanation is satisfied in
Figure 33A which has the basal Black Stuart unconform-
ity as the horizontal datum.

Restoration required that several areas be approxi-
mated as to their bed length because it was not fully dis-
played within the cross-section. These areas are on the
northeast bank of Sunshine Creek! and on the ridge
system between Little River and Sunshine Creek. Esti-
mates of bed length were made as short as possible to

minimize shortening and maximize the topography of the
pre-Black Stuart unconformity.

The palinspastic reconstructions (Fig. 33) show con-
siderable variation in stratigraphic thicknesses along the
line of section. These thickness changes are partly a result
of Columbian tectonics, but are also in part deposition-
al variations. Because shortening has been minimized the
thickness variation is accentuated. Stratigraphy generally
thins to the west with a prominent arch in the area now
northeast of Sunshine Creek.

‘Informal name used in this report for the first tributary draining southeastward into Separation Creek.
