Layer: Till Grain Size (ID: 0)

Name: Till Grain Size

Display Field: SAMPLE_ID

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: For grain size analysis, till samples are dry sieved to the <2 mm fraction. This fraction of the till sediment is subjected to hydrometer grain size analysis to determine the percentages of sand, silt, and clay. The process is based on the hydrometer method of Bouyoucous 1962.Sand: 63 µm to 2 mmSilt: 2µm to 63 µmClay: < 2 µmBouyoucous, G.H. (1962) Hydrometer Method Improved for Making Particle Size Analysis of Soils. Agronomy Journal, 54, 464-465.This feature class was created in 2019 and will be updated on an annual basis.Records in this layer can be related to records in other surficial geology layers (e.g., TillSampleSites1986_2014, TillSampleSites) using the values in the SAMPLE_ID field.
