Terrain factors influencing forest type distribution on a calcareous terrain in western Newfoundland were investigated. Landform elements were mapped at a scale of 1:12,500 utilizing air photo interpretation. Minimum and maximum elevation data along with dominant forest type occurrence were determined in the field. Frequencies of landform element and forest type correspondence were tested using a log-linear G2 analysis. Additionally, elevational differences of both landform elements and forest types were analyzed using the Kruskal-Wallis test. Null hypotheses of no significant landform influence on forest type distribution and no significant elevational differentiation of landform elements were rejected. However, no significant direct elevational differentiation of forest types was detected. Results are supportive of the observations of Damman (1967), indicating a primary toposequence control on forest type distribution. Verified forest type–landform associations could aid the development of a statistically based phytogeomorphic mapping system for forest land use management in Newfoundland. Key words: forest type, landform element, phytogeomorphic mapping, air photo interpretation

An outlier of sedimentary rock assigned to the Gowganda Formation of the Huronian Supergroup was discovered during field mapping in the Goulais River area, District of Algoma, Ontario. This outlier is the northernmost documented occurrence of Huronian sedimentary rocks in the Algoma region. The outlier is 53 m in stratigraphic thickness and consists of polymictic to oligomictic paraconglomerate and orthoconglomerate with interbeds of pink arkose, siltstone, and dark grey greywacke. The conglomerates contain metavolcanic fragments and altered feldspars that suggest part of the sediment had a nearby source. Hematite results in a pink matrix in both conglomerates and arkosic interbeds and may indicate that an oxidizing environment prevailed during deposition. Air photo interpretation may help locate other outliers in the vicinity of lineaments, faults, or topographic highs.

In the 1968 summer field season a reconnaissance investigation was made of the Quaternary geology of the region of Nordre Strømfjord (67°30'- 68°00'N) and Nordre Isortoq (north side) (67°12' N). From the field observations and supplementary air photo interpretation a preliminary map at 1:50 000 is being made of the area, which totals 8000 km2. This was a one-season project to provide data for a regional map of the Quaternary of West Greenland.

The aim of the field work in 1979 was to provide a stratigraphic framework which, together with later air-photo interpretation, will make possibIe the drawing of a 1:500 000 Quaternary map of the area. We concentrated our work on localizing and dating the outer limit of maximum ice cover, and on determining when glaciation started, and at what time the present distribution of ice was achieved. However, much work was also done on the pattern of isostatic readjustment and, in easternmost Peary Land, investigations were made on a c. 100 m thick sedimentary sequence of pre-Holocene age at Kap København.
