Preliminary surficial geology and mineral exploration considerations, Yellowknife area, N.W.T. Photos
| Photo 1. Extensive granitic outcrops east of Yellowknife, with glaciolacustrine sediments (covered by spruce) occurring in depressions associated with joints and fractures. |
| Photo 2. Washed till veneer forming sandy gravel lag over bedrock, northwest of Duncan Lake. |
| Photo 3. Poorly sorted glaciofluvial deposits, northeast of Yellowknife. Note concentration of rounded boulders on surface resulting from winnowing of fines by wave action. |
| Photo 4. Large peat bog underlain by glaciolacustrine sediments, northwest of Yellowknife. |
| Photo 5. Glacially-fluted granitic outcrops recording ice flow towards the southwest (right to left), east of Prosperous Lake. |
| Photo 6. Bedrock surface showing evidence of striae at 230 (upper section of photograph) cross cut by younger striae at 212 (lower part of photograph), north of Yellowknife. |
