ABSTRACTThe morphology and surface characteristics of the Soler Glacier, Patagonia, were analyzed utilizing vertical aerial photographs taken in 1984 and 1986, coupled with a field survey. The bedrock topography was measured in a gravimetric survey. The three subglacial cross-profiles indicate that a longitudinal subglacial ridge runs roughly along the median of the glacier. The major surface features recognized include an ablation medial moraine, ice-cored lateral and supraglacial moraines, ice mounds, crevasses, supraglacial stream systems, and five sets of ogive patterns.Ogive band spacings indicate that ice flow velocities range from less than 100 m yr-1 near the snout to more than 300 m yr~1 below icefalls and bedrock cliffs. These values generally agreed well with the distance ice mounds moved and the velocity inferred by extrapolation of two short-term field measurements.

Sedimentary facies and landform genesis at a temperate outlet glacier: Soler Glacier, North Patagonian Icefield

“…In this paper, the focus is on Soler Glacier, an ≈6‐km‐long outlet valley glacier on the eastern side of the North Patagonian Icefield. The total area of Soler Glacier in 1985 was 50·9 km 2 , with accumulation and ablation areas of 36·4 km 2 and 14·5 km 2 respectively (Aniya & Naruse, 1987). The glacier is fed via an icefall from the icefield and by icefalls and snow avalanches from the south‐eastern slope of Cerro (Mt) Hyades.…”

“…The glacier is fed via an icefall from the icefield and by icefalls and snow avalanches from the south‐eastern slope of Cerro (Mt) Hyades. In the 1980s, flow velocities ranged from 100 ma –1 near the snout to 300 ma –1 at the base of the main icefall, and the glacier was temperate throughout (Aniya & Naruse, 1987).…”

Recent behaviour of Glaciar Upsala, a fast-flowing calving glacier in Lago Argentino, southern Patagonia

“…So far, the only annual velocity data measured in the field exist for Glaciar Moreno (Skvarca and Naruse, 1997; Rott and others, 1998; Stuefer, 1999). However, annual flow velocities have also been estimated by measuring the movement of supraglacial debris (Aniya and Skvarca, 1992; Skvarca and others, 1999) and ogive waves (Aniya and others, 1988; Aniya and Sato, 1995).…”

Utilization of 6 × 6 cm format vertical aerial photographs for repetitive mapping of surface morphology and measurement of flow velocities of a small glacier in a remote area: Glaciar Soler, Hielo Patagónico Norte, Chile

“…The elevation ranges from 3078m (top of Cerro Hyades) to about 350 m, but much of the accumulation area in the icefield lies at 2000–2200m. The accumulation–area ratio (AAR) is 0.73, with the equilibrium-line altitude (ELA) located around 1350m (Aniya and Naruse, 1987). From estimation of the ELA in the field in 1985 (Cassasa, 1987), and interpretation of vertical aerial photographs taken in 1975, the AAR was estimated (Aniya and Naruse, 1987).…”

“…Of the seven surface ice-flow features of the ablation area, all of which are fed through an icefall or by avalanches, wave ogives develop only on the B2 feature, while band ogives develop on the B1, B4, B5 and A1 features (Fig. 2 inset; Aniya and others, 1988). Among these band ogives, those that developed on the B5 feature are most distinctive, followed by those developed on the A1 feature.…”
