Three Point problem with final solution

3D Model

This model demonstrates the final answer to the ‘3 point problem’. In addition to the first plane constructed (shale/limestone boundary), students are also told that the base of the limestone is 100 metres underneath, with sandstone below that. The hills above 2200 metres are capped by basalt. There is also a narrow dolerite dyke dipping at 60° toward the north.

The topographic surface represents and area of approximately 1.8 × 2.8 kilometres. Initial view is looking toward the northeast corner of the map area. Countour interval is 100 metres.
