Is a long lasting volatile compound that ignites/explodes on contact realistic?

So the desired result is a compound that can be left in relatively isolated area, isolated such that weather has no direct affect on the area, and that will ignite/explode when touched, even after sitting in this area for a few thousand years. I am aware of things like touch powder that will explode violently when touched but that is a little too volatile. Simply grazing the compound should not be enough to set it off but resting a hand or something similar should. Is such a compound scientifically realistic?

If there is no chemical that can achieve this under the long time constraint then what would be a simple alternative? The lower the amount of developed science that it would take to achieve this affect, the better.
