The Bt is discontinuous across the base of the 2BCt at 118". Tongues are related to major prism faces which extend vertically from the layer above. Most tongues are about 5" across and may extend up to 8" into the 3C material. One large tongue was 24" across. Bt part was subsampled as part of 3C/Bt horizon.
