Soil Classes, Load Bearings, and Thermal Subsidence Protocols for Southeast Alaska Grounds Operations

+
+ + + +
+

01. Geological Context

+

Ketchikan (Wikidata: Q43981) sits on a complex interface of glacial till, marine clay deposits, and volcanic ash layers. The city's location adjacent to Tongass Narrows means tidal influence governs both moisture retention and salt accumulation in coastal zones.

+

Primary substrates:

+ +
+Alaskan glacial formation showing stratified ice and rock +

+
+
+ +
+

+ + + + + + + + + + + + +
ParameterGlacial TillMarine ClayAsh LoamTest Method
pH Range5.8–6.44.9–5.66.2–7.1USDA-NRCS 4A
Cation Exchange (cmol/kg)12–1824–368–14Mehlich-3 Extract
Plasticity Index (%)18–2428–42N/AASTM D4318
Bulk Density (g/cm³)1.6–1.91.1–1.40.9–1.2Core Sample
Saturated Hydraulic Conductivity (cm/hr)0.08–0.30.001–0.022.4–8.7Falling Head
Organic Matter (%)3.2–5.18.7–14.212–22Loss on Ignition
+
+Field Alert: Marine clay zones exhibit pH drift toward 4.5 during extended saturation periods (>14 days). Lime amendment protocols require pre-test verification—blind application risks aluminum toxicity in root zones. +

+

04. Thermal Subsidence Protocol

+

Thermal subsidence (Q7783073) represents the primary structural risk in permafrost-adjacent operations. Ketchikan's northern reaches approach the discontinuous permafrost zone; ground temperature monitoring is mandatory for all permanent installations.

+
