AMUND HF.LLAND SOM BANEBRYTER I NORSK GEOLOGISK DISKUSSION
Derfor har det igrunden endnu større interesse, at et arbeide i
lignende retning av nok en nordmand fremlægges i verdens største geo«
logiske selskap av en anerkjendt foregangsmand netop paa heromhandlede
omraade. Det vil derfor ved denne anledning ogsaa være paa sin plads,
at vi mindes enkelte træk fra denne avhandling:
«A Norwegian geologist travelling in North Greenland,» sier Helland,
«will find much that is new to him, but perhaps still more that is familar
–-Like the west coast of Norway, Greenland is intersected by many
large fjords, which, when not filled wholly or partially by glaciers, pierce
deep into the country. In front of the fjords near the open sea there is
a «Skärgård» of larger and smaller islands, perfectly resembling the
«Skärgård» of Norway. Generally the part of Greenland nearest to the
sea, or «the outer land», which is not covered by eternal snow, strikingly
resembles the outermost skerries and islands on the west coast of Norway,
both in the rocks and in the configuration of the islands. The hills
around the fjords in North Greenland vary much in height, being some«
times ridges only a few hundred feet above the sea, sometimes mountains
4000 feet, and occasionally even 6000 feet or a little more.»63 Og videre
fortsætter han: «We can constantly explain the Glacial phenomena of
Norway by reference to Greenland — — — Greenland at present affords
us a picture of Norway about the end of the Glacial epoch.» 64 Og idet
Helland omtaler «raerne» med bakenfor liggende sjøer i Smaalenene og Jarls«
berg, sier han videre: «the phenomena are so regular that one might suppose that
Professor Ramsay had propounded his theory of the Glacial formation of lakes
with special reference to these; this theory elucidates the whole.»65 Det
er her av betydelig interesse at merke sig Ramsay’s egen omtale av «lakes,
many, if not all, of which lie in true rock«basins, a fact which I inferred
in my memoir on lakes published in 1864, and which has since been
proved by Mr. Amund Helland, of Christiania, in his late memoirs, a
summary of which is given in his paper ’On the Ice«Fjords of North
Greenland, and on the Formation of Fjords, Lakes, and Cirques in Nor«
way and Greenland’» 66. Og det har sin store interesse at minde om de
ord, som Ramsay lar falde om Hellands arbeide: «Though I have no doubt
that many seaward extensions of land valleys, now fiords, were once dry land
valleys themselves, and that the deeper hollows in them were sometimes
excavated when the whole stood above the level of the sea, yet this is
not essential, for as has been observed by Mr. Amund Helland in his
masterly papers (already quoted) on the Glaciation of Greenland, Norway,
and Sweden, if a great glacier be sufficiently powerful to push onward,
