When we camp in rainforests or even country side forest, we are supposed to be very careful about Reptiles, especially Snakes. In India out of the many venomous snakes, I have found Pit Vipers to be very common.
That is why I have always considered the possible threats while choosing a campsite.
But at Higher altitudes, like the Himalayas I do not have any information regarding their habitats. If I google it, I may get the information that I need. But, as far as I know and what I have learnt about Vipers, is, they have an organ called Jacobson's Organ which makes them to sense the heat signatures.
In regions around Mt. Everest (where I will be going), in Sagarmatha National Park, they have this Himalayan Pit Viper. I have confirmed that from a friend who is a Herpetologist and has worked in that region but never have had a chance to study the Himalayan Pit Viper.
For my question, this himalayan pit viper is just an example in case of Himalays, there can be many other species than Pit Vipers. I chose to ask w.r.t this because it is commonly found there. In other parts of the world, I believe there are Venomous Snakes, for that matter this question can also be taken as part where it generally snows!
My question is: If it is true about Pit Vipers being able to trace the heat signatures, does camping in the areas where it snows unsafe? Because, when it snows, it's obviously cold, and so is our body temperature. Yet, will one such reptile be able to trace the heat signature?
