Bıstrup had to make a considerable detour in order to climb it. 
The height of the mountain is 875 m; the ascent was difficult; the 
mountain was at its upper, dome-like part covered by a water-filled 
névé, which one could only cross with great difficulty. 
When Bisrrup reached the highest peak of the mountain, he 
realized that it would mean considerable labour in observations, and 
also that the latter, owing to the position of the mountain, would 
require two stations. Bisrrup was, however, already then so worn 
out with the ascent, that he had of necessity to perform the work 
in the easiest manner possible. 
Bıstrup’s pocket book contains the following notes of the con- 
ditions, under which the measuring was performed. 
“After several days of fog and wind we got clear and calm 
“weather 31/V. We left the tent at 5.45 a. m. and reached the peak 
“at 9.15. It was then too late to make a determination of time, and 
“as I was quite sure that I could see the Cairns XV and VIII and 
“with less certainty Cairn VI, I began a trigonometric station pointing 
“by means of XV—VIII—VI— Haystack — Peak С in Besselbay — 
“and a remote discernible peak which I suppose to be one of the 
“trigonometrically determined points of the Germans. At the beginning 
“of the observations the weather was almost calm, but the wind 
“increased more and more, and our position became extremely dis- 
“agreeable, and the more as we were very wet owing to our wading 
“in loose snow up to our hips. I at once gave up building the cairn, 
“as everything was covered with snow, and only a few stones pro- 
“jected from it. The observations I dared not put off for fear of fog; 
“there was a good deal of fog across Koldewey and Stormbugten, so 
“that I could not know, when it might begin to hamper my move- 
“ments. Therefore I could not make sketches from the two stations, 
“nor was it strictly necessary, as most of the points, mountains &c. 
“had already been sketched from other stations. Dronning Louises 
“Land was not visible throughout its whole extent; only a few peaks 
“were discernible; the rest were mixed up with each other, so that 
“on a drawing it would not have been possible to make anything 
“out of it. The distance was too great, the light was not good and 
“the air not clear. At a single spot I thought I saw the inland ice 
“behind Dronning Louises Land, but I am not sure.” 
In reality, of the six points mentioned above as serviceable for 
the station pointing, only the positions of the three cairns XV, VIII 
and VI were known, and even then it was doubtful, whether the 
last mentioned cairn could be seen. It was, therefore, necessary to 
perform an observation of latitude and azimuth, in order to obtain 
a control of the observation. The observations after this included:
