Appendix 3. Photographs of till: A selection of colour photographs of various till facies, from different glaciological, geological, and geographical settings. Photos 1 to 6 illustrate various types of subglacial traction tills that have been sampled for regional surveys by experienced Quaternary researchers across Canada. Photos 7 to 12 show those same tills, and how they would appear when sampling them. Photos 13 and 14 are of meltout tills, that may be sampled in proper context but care must be taken when interpreting the results from those samples. Photo 15 shows a colluvial deposit, comprising till that has been reworked into a gravity flow deposit. Appendix 3-Photo 1. Dense overconsolidated silty sand subglacial traction till with oxidation (organge iron staining) on the joint planes, from a till exposure overlying carbonate bedrock, southwestern Northwest Territories, northern Canada. Note that most of the clasts are subrounded. Knife for scale. Photo by Roger Paulen. Appendix 3-Photo 2. Moderately ...
