We construct a sequence of Heegner points on E, defined over a $Z_p^{\infty}$-tower of finite extensions of k, and show that these Heegner points generate a group of infinite rank. This is a function field analogue of a result of C.Cornut and V.Vatsal14 Pages, LaTeX; Minor changes made; To appear in Journal of Number TheoryNumber Theory11G05; 11R58text
