For a nonparametric prescribed mean curvature surface \(z=f(x,y)\) in a vertical cylinder \(\Omega \times \mathbb {R}\subset \mathbb {R}^{3},\) the existence and behavior of the radial limits of f at a nonconvex corner \(\mathcal{O}_{2}\in \partial \Omega \) are well studied and understood. For a nonparametric prescribed mean curvature hypersurface \(z=f(\mathbf{x})\) in a vertical cylinder \(\Omega \times \mathbb {R}\subset \mathbb {R}^{n+1},\)\(n\ge 3,\) at a nonconvex corner \(\mathcal{O}_{n}\in \partial \Omega ,\) the boundary behavior of f is largely unknown. We shall consider the specific example of a nonparametric minimal hypersurface in \(\mathbb {R}^{4}\) and investigate its behavior at a nonconvex conical point of the boundary of its domain.
