THE INTERIOR--KERLINGARFJÖLL

E LOOKING TOWARDS KERLINGARFJÖLL.]
When preparations had been completed, some of us started for the
mountains of Kerlingarfjöll, where high up, among the snow and ice,
there are hot springs, fumaroles, and solfataras. The party was a small
one. Thomas, Hill, and I started with the conductor and two guides.
Unfortunately Thomas's side was giving him "fits," and he had to return
after going but a very short distance.
We had a big quicksand river, the Jokulvisl, to cross--a river that
is often highly dangerous, and sometimes, when the water is "up,"
unfordable. We were accompanied so far by the "nautical adviser" and
the "handy man," who afterwards proceeded up the river to view a very
fine gorge in it, which we saw from the other side. The journey was
most interesting; we crossed vast moraines, where enormous erratics
were dotted about on the surface, before we reached the Jokulvisl.
The guides all had a great dread of this river; but we made a good
crossing, for the recent cold weather had retarded the melting of the
snow, and there was no flood in the river, though it was running very
swiftly. The sensation when crossing these swift-running rivers is
very uncanny--one seems to be rushing up-stream against the current,
and on looking at the ponies and their riders in front the impression
is deepened: they seem to be moving rapidly as the water rushes by and
foams round them, but really the pace is very slow, for the ponies
plod along steadily through the water. Even if those in front could
be ignored, the impression of going rapidly up-stream could not be
effaced, for the water would rush by and swirl round one's own pony
just the same. It might be thought that a glance at the opposite
bank of the river ought to dispel the illusion, but even that does
not correct the false impression. After crossing the Jokulvisl, we
proceeded along its banks for nearly a mile to where the river has
carved its way deep down through the lava, and left sides that rise
vertically for a hundred feet or more. There is a fine hard dyke in one
place extending into the river, on the end of which a pinnacle rises
that adds much to the grandeur of the scene. After photographing this
gorge, we proceeded across more moraine matter until reaching some of
the main blocks of the Kerlingarfjöll mountains. In these moraines we
had very steep slopes to ascend and descend; in one case the descent
was so sharp that for safety we all dismounted and led our ponies down
the side, at each step sending down a shower of stones and pebbles. At
Kerlingarfjöll we suddenly came upon a series of inclined snow-fields,
one of which we ascended, traversing it from end to end. It was more
than a mile long, but the zigzag course that we had to pursue made
it seem almost interminable; as it was, we were nearly an hour making
the crossing. The photograph shows the members of the party apparently
soaring up to heaven on their ponies, who in their wild flight seem to
be emulating Pegasus. Soon after we had started up this snow slope,
the clouds descended upon us and we were enveloped in a thick mist; we
could see nothing but just a very limited circle of snow around us, and
thus we proceeded, zigzagging the whole way. We crossed several other
snow-fields, but they were of less extent.

[Illustration: KERLINGARFJÖLL--FIRE AND ICE.]
When approaching the hot springs, we became aware of their nearness by
the sulphurous smell that came wafting towards us. Suddenly, from a
ridge, we beheld a most wonderful and awe-inspiring sight. All around
there were snow and ice-fields, and from their midst, but on the far
side of a deep valley that intervened, there rose a cloud of steam,
the strong sulphurous smell of which suggested the nearness of the
lower regions. There was a mass of yellow, brown, green, and blue
clayey matter--liparite softened by steam it was--that had been cut and
shaped by ice, snow, and water into a series of cones and cone-like
surfaces, and from crevices in this clay the sulphurous steam escaped.
Below was the deep intervening valley, the valley of the Ásquidsá,
a river that flows from the upper heights of Kerlingarfjöll. To get
down to this stream was a work of no slight difficulty; it required
patience, much hard work, and much coaxing of ponies. We rode through
the snow, and slid down steep slopes of various-coloured clay. These
slopes became so precipitous at last that we all had to dismount
and plod along their sides, coaxing our unwilling steeds to follow.
Presently we reached what looked very much like an _impasse_ at the
end of a valley, the sides of which had gradually converged until
the channel was then scarcely wider than the ponies were broad. The
guides were not to be beaten, however, for they proceeded on foot, and
literally dragged the ponies one by one down this channel, to where
the snow came to an end and there was a drop of two or three feet
into a small stream of water. The guides splashed into this, and by
dint of much coaxing induced the ponies to follow, leading them along
the stream. Right at the end there was a small waterfall, with a deep
pool below. Down the fall they slid, splashing into the pool, where
they stood panting beside the main stream that we had seen from above,
which ran at right angles to the smaller stream. Meantime, Hill, the
conductor, and I had been walking at a slightly higher level on the
top of a gradually descending spur of clayey matter. Down the slope of
this we scrambled on all fours, carrying with us several pounds' weight
of the clay on each boot, to say nothing of what we had on clothes
and hands. From the side of the steep slope we mounted our ponies,
considerably heavier than when we had been on their backs a few minutes
before. We crossed the stream to the hot springs. Some of the ponies
objected to passing the hot, steaming holes, and absolutely refused
for a long time to do so; but eventually all were coaxed or dragged
by. To describe the place is impossible, and mere words are inadequate
to explain the nature of the scene. Photographs that I took do not
give much idea of the place, for they are all more or less failures.
It differs from anything that I saw in New Zealand, because in the hot
spring region in the North Island there is no ice and snow. I took a
boiling-point observation for altitude, and found the elevation of the
stream at the foot of the burning hill to be 3088 feet above sea-level.
I hurried over lunch, and set off with Hannes, one of the guides, to
try to do some plane-tabling; but the Fates, in the shape of dense
mist, were against me, and prevented me from seeing anything more
distant than a few hundred feet. On the upward journey I had noticed a
good position for a new station. On the way down to the spot chosen,
which was below the long snow slope, we mistook our way in the mist,
and went down the wrong slope, coming to an almost sheer descent
before finding out our mistake. We learnt this just in time, however,
to prevent a catastrophe. We retraced our steps by the tracks in the
snow, until we reached the right slope, and there struck the zigzag
track made on the ascent. The intended new station was reached without
further incident occurring.
From the glimpses of the country that I had obtained on the upward
journey, I was convinced that to make a map of these mountains
(Kerlingarfjöll) would require a week of fine weather and a series of
camps on the spot. As nothing of much value could be done in a few
hours, I did not lose very much by the mist having descended over the
country, except the exceedingly fine views. It was disappointing not to
be able to get to work with camera, but under the circumstances nothing
could be done except growl at adverse luck.
After waiting an hour or so for the rest of the party--Hill, the
conductor, and Sigurthur--who came on more at their leisure, we resumed
the descent towards the plains. Suddenly we got below the line of
drifting clouds, and there we beheld some wonderful sights--remarkable
scenes due to a series of rapid atmospheric changes. A small lake
in the lava-field suddenly came into view as we reached the line of
the reflected sunlight. The lake shone out, gradually increasing
in intensity, until it glowed brilliantly with a marvellous light.
The effect as the scene opened out beneath the clouds was weirdly
wonderful. Some of the clouds were of a deep blue, almost purple, tint,
producing, as they overhung a line of bright light and vivid colouring,
a most impressive picture. Away in the distance, on Lake Hvitarvatn,
we could see icebergs floating in their hundreds. These bergs were
great blocks of ice that had broken away from the glaciers flowing
from Lang Jökull into the lake. The return journey was accomplished,
without the occurrence of any untoward incident, at a rate that showed
of what stuff the ponies were made, for they cantered over the roughest
of moraines with scarcely a stumble, and we made excellent time to our
camp at Gránanes. There we found that a real fire had been conjured
up in our absence, and a successful attempt made to bake bread in a
wash-hand basin--an instance of the shifts that had to be made, which
were many and various.
When passing over the sloping moraine matter towards Kerlingarfjöll we
crossed a number of peculiar terrace formations, and we often found
similar terraces on the hillsides in other places also. These terraces
have edges or banks of vegetation, which seem to grow in irregular
lines and to arrest the natural descent of alluvial matter, forming a
series of terraces or steps that rise, as a rule, but a few inches one
above another. The vegetation also collects some of the wind-blown sand
of the deserts, which thus assists in the formation of the terraces.
