A view from Grindelwald, near Interlaken, Switzerland.
The tree line is the edge of the habitat at which trees are capable of growing. It is found at high elevations and high latitudes. Beyond the tree line, trees cannot tolerate the environmental conditions (usually cold temperatures or associated lack of available moisture). (source) This particular tree line is in the Swiss Alps.

Treelines always speak to me as symbols of pushing things to the limits and then reaching the point of realistic realisation and endeavour that it can go no further. Marvellous image.

That’s an excellent interpretation, Don. I can’t imagine life for the highest tree is very easy! But nature will fill every niche it possibly can.
