4. Does the data set describe conditions during a particular time period?

   Beginning_Date: 25-Jun-2022

   Ending_Date: 18-Oct-2024

   Currentness_Reference:

   Ground condition at time data were collected. Watershed soil and a delta-front sediment core were collected ten months after the 2021 Muckamuck Wildfire in June 2022. Passive samplers were deployed in June 2022 and August 2023 to measure North Fork Salmon Creek water chemistry. A vibracore was collected in October 2023 near the reservoir outflow.

5. What is the general form of this data set?

6. How does the data set represent geographic features?
   1. How are geographic features stored in the data set?
      This is a Point data set. It contains the following vector data types (SDTS terminology):
      • Point (87)
   2. What coordinate system is used to represent geographic features?
      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.0001. Longitudes are given to the nearest 0.0001. Latitude and longitude values are specified in Decimal degrees. The horizontal datum used is D_WGS_1984.
      The ellipsoid used is WGS84.
      The semi-major axis of the ellipsoid used is 6378137.0000.
      The flattening of the ellipsoid used is 1/298.2572.
