Measurements from six Ogo 5 particle and field experiments are used to examine the structure of the earth's bow shock during a period of extremely high &bgr; (the ratio of plasma thermal to magnetic energy density), as determined from simultaneous measurments of the upstream plasma on Heos. Even though the interplanetary field is nearly perpendicular to the shock normal, the shock is extremely turbulent. Large field increases are observed up to a factor of 20 above the upstream values. A head of these large enhancements, smaller magnetic effects accompanied by electrostatic noise, electron heating, and ion deflection are observed for several minutes. These observations suggest that a steady state shock may not be able to form at very high &bgr;. Further, they show that while the magnetic energy density may be relatively unimportant in the upstream flow, it can become very significant within the shock structure, and hence the magnetic field should not be ignored in theoretical treatments of very high beta shocks.
