Hike south on the Chalone Peak Trail, uphill past Gertie's Pinnacle, about 10 minutes to a ridge trail that leads north towards the Yaks. This ridge trail is a better approach to Kasparek's and Yaks than the trail shown in the guidebook. Just south past this trail junction is an east-facing wall with a midway ledge. This is Cortadura Wall.

  of a groove with a bush at the top.  Off the trail, boulder up
  past the bush and gain the main ledge.  Up above there is a waterchute
  which splits in two.  Go up the right side to the right hand
  waterchute.  Pro: thin #0 TCU to 1.5 Friend plus 4.5 Friend
