Not exactly a plant hunting excursion but a nice trip anyway.
Last time it was vacation, very fine weather and flowering plants all places, this time it was work, cloudy and the fall had arrived; but interesting anyway.
We didn't go far from Longyearbyen either but had to bring guns anyway. (My daughter who is a student up there now told me she has to bring a gun every time she is going to pee behind a boulder when she is out in the fields!)
Adventdalen (The Advent Valley) in fall colour. Adventelva (The Advent River)
This German plane is from WW2. Adventfjorden (The Advent Fiord)
Hjortfjellet and Operafjellet (fjellet = the mountain). The EISCAT radar used to study interactions between the Sun and the Earth.
Breinosa, at about 600m it isn't many plants. The rocks are part of a vast block field. Up here only mosses and lichens grow (and the Svalbard poppy).
