Location 4 is opposite location 1, and the eastern glacier stream flows between location 1 and 4.
2016 - 2017: As expected, nothing much has changed here. To the left of the striking gravel/ice hill, a new 20m high funnel with a small lake in front of it has formed.

This repeat photos shows the formation of an erosion ditch in the glacier forefield of Gamchi glacier. On 12.7.2015 the majority of the water flowed off to the east (to the right in the photo). No erosion ditch was yet visible. On 8.7.2016 (= one year later) the prominent erosion ditch existed already in the same size as in the summer of 2019. Photos showing the size of the erosion ditch with the help of a person can be found on the page with the description of the term 'Erosion ditch'.

18.07.2024: The last panoramic photo taken from this location. During the night of 1./2. August 2024, an erosion gully opened up during a heavy rainfall event. The boulder from location 15 fell into the erosion gully.
In June 2017 we observed for the first time a newly created lake, which is surrounded by ice on the valley side. By the beginning of September 2017 the lake has grown in size and probably also in depth.

This comparison shows the formation and development of the proglacial lake, which was formed in late 2016 or early 2017 and emptied in September 2019. In the following years, an impressive erosion trench has formed. View from eastern lateral moraine.

On the photo from 2013 you can see the iron ladder over which the mountain path led at that time.
On the photo from 2019 you can see the remains of the lake, which was formed in June 2017 and leaked in September 2019.

14.08.2019: Behind the ice was was the glacial lake at that time. The clear transition from the glacier ice to the underlying moraine material is clearly visible on this photo.
This before/after photo comparison shows the evolution of the ice wall during 12 months. During these 12 months the small glacial lake behind has emptied and a part of the ice wall has collapsed.

These repeat photos show the melting of the ice bar that had dammed the glacial lake. Further how the terrain changes after the melting of the ice.
The surroundings of the tripod location are still quite unstable. Presumably, the shooting location itself has also sunk a bit. A hundred percent accuracy of fit is therefore hardly feasible without cheating.

This comparison shows the situation in the western part of the Gamchi glacier. In July 2015 we discovered a flat, newly created glacial lake in front of a large portal. A year later the lake did not exist any more and until September 2017 a lot of ice melted away.

23.06.2020: A lot of snow has already melted. The glacier ice is exposed to the sun's rays and heat and melts.
02.07.2021: There is still a lot of snow. The glacier ice is quite well protected from the sun's rays and heat until the snow has melted.
Lots of snow at the beginning of summer does not necessarily mean that the glacier will have increased in mass and/or length by the end of summer.
These repeat photos show how different snow conditions can be in early summer.

17.06.2022: Since June 2020, stones and debris have come loose from the steep side walls of the erosion ditch. This material has been deposited at the foot of the side walls. The previously almost U-shaped cross-section of the trench is moving towards a V-shape.

The cross section of the tunnel on the left has strongly enlarged while its length is shrink by the collapse of the rear part to about half. Possibly already in this summer the meanwhile thin cover of this tunnel will also break.
The span of the portal (right) has decreased. The funnel above the portal is much more powerful than a year ago.
The scree slope, from which the photographs were taken, has also changed since July 2010. It was therefore not easy to find exactly the same point for shooting.
Between July 2011 and July 2012, the left bow of ice has collapsed.
