NTSB narrative
The pilot said that he spoke with other pilots before the flight to determine the soaring conditions. The pilots he spoke with reported that the lift conditions were not great but were generally satisfactory. A glider instructor pilot told him that there were areas of lift and areas of sink out there, but that there shouldn't be a problem making the airport from where he was let go from the tow plane. The pilot stated that after release from the tow plane he experienced 'a little bit of lift and then a huge sink rate and couldn't make it over the ridge' that separated him from the airport. He realized that he would not make it back to the airport and attempted to make a forced landing southeast of the airport and collided with ground obstructions during the landing roll.
Probable cause
The pilot's inability to maintain a proper glide path due to an inadvertent encounter with an area of high sink rate conditions. The mountainous/hilly nature of the terrain which limited the pilot's selection of a landing site is a factor.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
