I agree with John and Fred that the top photo is Horsetail(Equisetum arvense). The photo you have Tommy is of the fertile stalk. The Horsetail produces two different stalks,one being the infertile Horsetail with twiggy like foliage and the other the fertile one(as in your photo) which produces spores,these spores are wrapped with small bands the unwrap in dry weather which work like a parachute to carry the spore on the wind. It also contains silica,silicic acids plus saponins so its good for scrubbing your camp cookwear.
