About this layer
Current mineral tenure shows mapped mining rights, licences or permits. Check the record type and status together with land-access information. A mineral boundary does not by itself establish who may enter or prospect.
What it is for
Check the legend, status and available record details. Confirm the current record and relevant access arrangements before visiting.
Limits
Applications and granted rights are different. A mapped boundary alone does not tell you whether detecting is permitted.

About this layer
These records identify mapped recreation sites. They help you research facilities and managed places near your route. Check the site rules; a recreation site is not necessarily a permitted detecting area.
What it is for
Turn on the relevant layers together and read their legends and notes. Check current conditions with the land manager before planning a visit.
Limits
An unshaded area is not automatically available for detecting. Different permissions and restrictions can overlap.

About this layer
Historic claim maps show where claims were recorded and later closed. Concentrations help you research patterns of earlier mining interest. Closed claims do not establish that land is currently unclaimed or open to detecting.
What it is for
Compare historic activity with current tenure, geology and access layers when researching an area.
Limits
An expired or closed record does not mean land is now open. Check current records and permissions separately.

State Geology

State GeologyExplorer
Geologic Map of Alaska
The USGS statewide Geologic Map of Alaska at 1:1,584,000: one unit list for the whole state, with each unit's rock types and age. Coarser than the detailed state geology, it covers the ground the detailed maps have not reached. Open the filter to search the units or show only the gold host rocks.

About this layer
Geological maps divide the ground into rock or sediment units. Colours and patterns tell you which mapped unit is present; use the legend to read them. Compare the boundaries with mineral records, without assuming one rock type guarantees gold.
What it is for
Use the legend to identify colours and line symbols. Compare rock boundaries and structures with mineral records and terrain.
Limits
Geological maps simplify the ground at their stated scale. Boundaries are interpretations and may not match what is exposed at the surface.

Detailed State Geology
Alaska's most detailed published geology, joined from state geological survey and USGS maps: each area shows the best map available, from 1:24,000 quadrangles to 1:1,000,000 state maps. Rock units are coloured by type and age, with contacts, faults and strike and dip. Open the filter to search the units or show only the gold host rocks.

Terrain+™ LiDAR

© Mapbox, © Maxar
Terrain+™ LiDARPro
Terrain+™ Analysis
Outline an area of any shape up to 3 miles across over USGS 1 m lidar and see the ground full screen as a 3D surface, with a VE slider to raise or flatten it. Any layer can be draped over it. It shows Dynamic LiDAR™, turned on as it is built, and its LiDAR button sets Dynamic LiDAR™'s look on the model and the map alike: hillshade, slope, local relief, sky view and openness, multi-scale relief, VAT, red relief, Multi-Light PCA or the SVF/LRM Composite, each with settings to bring out the features you are after. Save a model with the button beside the X to keep it on the phone for 30 days and open it from the Terrain+™ LiDAR menu in the field, without a connection.

Dynamic LiDAR™
Dynamic LiDAR™ draws the USGS's 1 m lidar over the map on the phone as you move, from zoom 11 in, in any of Terrain+™'s relief renderings (hillshade, slope, local relief, sky view and openness, multi-scale relief, VAT and red relief), Multi-Light PCA or the SVF/LRM Composite.

Dynamic LiDAR draws the USGS 1 m lidar. No Alaska tile drew at the eight places tried (Fairbanks, Anchorage, Hatcher Pass, Girdwood, Hope, Juneau, Sitka, Nome), so this is the same engine over California. Satellite imagery © Mapbox, © Maxar.
