From Rdokass to the Concordia Aiupliitlieatre. 20j The first observer to call attention to these ice pyramids was God\vinAusten, whom nothing noteworthy escaped. Giiillarmod supposes themto be seracs fallen from overhanging side glaciers, and reduced to thisshape by melting. Ferber notes the phenomenon without attemptingan explanation. They seem to be peculiar to the Baltoro—at least, theice cones and pyramids seen by the Workmans on the Hispar and byLongstaff on the Siachen, and the glaciers which cut into the upper. ICE Shyok valley, appear to be merely supports of fallen tables. In anycase, we have no detailed descriptions which would suffice to identifythem with the pyramids of the Baltoro. These formations we observed only as far as the entrance to theConcordia basin. We saw iione of them on the higher portion of theglacier, where the action of melting is equally intense. But in theConcordia amphitheatre and on the upper Baltoro we saw formationswhich might account for the origin of the pyramids. I mean the longhigh dykes of ice which rise between the dark moiaine ridges hoUowedby melting. They are generally bare of detritus, possibly owing to the (9221) o 210 (Ii;i])ter XII. steepness of their sides, and stand out sliarply from tlio moraine-coveicdsurface as if the live ice had violently thrust itself up through the shroudof detritus.
