Figure 11.—Plunging Contact Surface between intrusive Granodiorite and Cretaceous Formation. Drawn from a photograph taken on the south side of the Castle Peak stock, near the point "D," figure 7. View looking east. Contact shown by heavy line, right center of view. Granodiorite on left, Cretaceous formation on right. The vertical distance be- tween the two ends of the contact line as drawn is 800 feet. The highest summit is Castle peak. body is thus neither a bysmalith nor a chonolith. The magma entered the tilted sediments, quietly replacing cubic mile after cubic mile until its energies failed and it froze in situ. Not only so; the superb exposures seen at many points in the deep can- yons trenching the granodiorite illustrate with quite spectacular effect the downward enlargement of the intrusive body. At both ends and ou both sides of the granodiorite body the steep mountain cliffs exhibit the mini-.
