Abstract: Let $ H$ denote the measure-preserving Hénon map with the parameter $ a > 0$. The map $ H$ has a hyperbolic fixed point $ \boldsymbol{p}$. The main result of this paper is that the unstable mainfold of $ \boldsymbol{p}$ is the iterated limit of a very simple set. Informally,

$\displaystyle W^u(\boldsymbol{p}) = \lim_{n\to\infty} H^n(\mathcal L) $

where $ \mathcal L$ is the line $ y=-x$ and $ W^u(\boldsymbol{p})$ denotes the unstable manifold of $ \boldsymbol{p}$.
