We present two families of solutions (g,{phi}) of the Einstein-Klein-Gordon system minimally coupled to gravity, massless scalar field equations possessing a regular RxS{sup 2} bifurcating Killing horizon. The solutions may be interpreted as describing the metric g and the field {phi} in an open vicinity containing the event horizon of a Schwarzschild black hole interacting with an exterior, static-axisymmetric distribution of matter carrying scalar charges generating {phi}. One family of the solution possesses a spherical bifurcation two sphere and may be interpreted as generated by a distribution of matter carrying scalar charges but of negligible self-gravity. The other family describes an axisymmetric horizon with the distortion caused by the self-gravity of the external matter. For both classes of solutions the scalar field {phi} relaxes into a configuration so that its energy-momentum tensor T{sup {mu}}{sup {nu}} on the Killing horizon obeys the property: T{sup {mu}}{sup {nu}}l{sub {mu}}l{sub {nu}}=0 where l{sup {mu}} is a null vector normal to the horizon. It is also indicated that the Einstein-Klein-Gordon system ought to admit distorted black holes characterized by an RxS{sup 1}xS{sup 1} event horizon.
