Near the creek's source, its elevation is in the range of 1165-1496 feet.
Using lidar (Light Detection and Ranging) datasets, we combined a semi-automated creek extraction algorithm, based on elevation and slope thresholds, with a novel algorithm for morphometric creek analysis.
This low-cost approach of temperature and specific conductance sensing in vegetated coastal wetlands where access, precise elevation control and creek discharge measurements are difficult, provides a simple way of tracking water masses when sufficient contrast exists between water sources.
The elevation of the creek's source is approximately 760 feet above sea level.
The elevation of the creek's mouth is 594 feet above sea level.
The elevation of the creek's source is between 1780 and above sea level.
The elevation of the creek's watershed north of the northernmost line of hills is in the range of 663-994 feet.
Annual precipitation at higher elevations in the creek's upper watershed is much higher, more than 70 inches.
NY 319 briefly descended to cross a creek then continued climbing, reaching an elevation of 1760 feet near Packer Mason Cemetery.
North of Cave Junction, US 199 leaves the Illinois River, which curves west towards the ocean, and follows several small creeks past Selma to Hayes Hill Summit (elevation about 1700 feet/500 m).
Over time, fine-grained sediments accumulate on creek banks and creates areas of high elevation, where Spartina can develop.
