Lichens as companions

We were huddled up in the shelter of this rock. Ten of us cramped in two four men tents as this was the only space available. Our rendezvous borasu pass beckoned us but we were to stay put untill early morning next day. There was not a soul around when these yellow spots caught my attention. hardy life! was where I just said there wasn't a soul around. The company of tenacious lichens gave us enough courage to hang on and cross the pass early morning the day after.
