Rock-fall potential in the Yosemite Valley, California
Gerald F. Wieczorek, Meghan M. Morrissey, Giulio Iovine, Jonathan W. Godt
1999, Open-File Report 99-578
We used two methods of estimating rock-fall potential in the Yosemite Valley, California based on (1) physical evidence of previous rock-fall travel, in which the potential extends to the base of the talus, and (2) theoretical potential energy considerations, in which the potential can extend beyond the base of the...

Land and mineral ownership coverage for the Uinta Basin, Wasatch Plateau and surrounding areas, northeastern Utah
L. H. Biewick, G. A. Green
1999, Open-File Report 99-553-B
This Arc/Info coverage contains land status and Federal and State mineral ownership for approximately 25,900 square miles in northeastern Utah. The polygon coverage (which is also provided here as a shapefile) contains three attributes of ownership information for each polygon. One attribute indicates whether the surface is State owned, privately...

Effect of baseline corrections on response spectra for two recordings of the 1999 Chi-Chi, Taiwan, earthquake
David M. Boore
1999, Open-File Report 99-545
Displacements derived from the accelerogram recordings of the 1999 Chi-Chi, Taiwan earthquake at stations TCU078 and TCU129 show drifts when only a simple baseline derived from the pre-event portion of the record is removed from the records. The appearance of the velocity and displacement records suggests that changes in the...
