You need a 4x4 to navigate the highland roads and numerous river crossings
Langafön snow slope on the west caldera rim of Kverkfjöll. Hveradalur steam visible to the right of Langafön.
Having a first look at lower Hveragil
A way down to lower Hveragil
The warmth and probably the alkaline water of Hveragil sustains a narrow strip of angelica plants – an oasis in the wastelands
Important to take a sample before taking a bath upstream
Travertine-covered pillow rims
A steaming waterfall blocks the path to middle Hveragil, but it doesn't matter. It is the perfect temperature for a bath.
Trying to find a route to the middle Hveragil valley
Askja has been covered in snow both times I have visited in late August
Steam-heated acid-sulfate lake Víti
A few fumaroles were waiting for us on Víti's shore.
Víti is a small phreatic explosion crater that was formed during the VEI-5 1875 eruption of Askja
Jói showing how fumarole sampling is done
Our prototype for fumarole condensate sampling for B isotopes
Noble gas fumarole samples are taken into copper tubes.
Sampling of diffuse fumaroles takes time
Hot springs slightly above water level of Lake Öskjuvatn
Lake Öskjuvatn is a 10 km2 caldera lake, formed after the 1875 eruption.
Mt. Herðubreið seen after sunset from Askja
Melt water stream sampling back at Kverkfjöll
Next day, snow was gone and we returned to Hveragil
Office mates posing with Snæfell volcano in the background.

Middle Hveragil valley
Here, the the river is hotter and the travertine deposits are thicker
Layered carbonate crust precipitates on the banks of Hveragil.
Andri sampling a thin spring seep on a tight, slippery spot
Our happy field crew of Dan Colman, myself, Andri Stefánsson, Maja Bar Rasmussen and Jóhann Gunnarsson Robin
Setting up for sampling Volga, a warm river that flows straight out of Kverkjökull.
A highland storm was on arrival, so we had to leave a day earlier.
Dr. Dan Colman sampling hot geothermal clay
We finally got to assist Dan in his sampling.
Our car was kind enough to get us out of the Highlands to the Reykjahlíð bus stop before breaking.
