Download the Siskiyou County Map files from this page as one high-resolution A3 JPG ZIP. The package includes a general county map, a ranked city-distribution map, and a terrain-and-water map. Together they show Yreka, Weed, Mount Shasta, Montague, Dunsmuir, Tulelake, the I-5 corridor, western state routes, and major water features such as the Klamath, Scott, and Shasta rivers, Copco Lake, Iron Gate Reservoir, Lake Siskiyou, Medicine Lake, and Tule Lake Sump. The WebP previews below are useful for quick viewing, while the downloadable JPG files are better suited to printing and document work.
Siskiyou County sits along California’s northern border with Oregon and covers a broad mix of mountain country, valleys, river corridors, and the more open northeastern part of the county. The county’s official overview identifies Yreka as the county seat and lists communities including Mount Shasta, Weed, Dunsmuir, McCloud, and Tulelake among the places that help define the region. On the supplied maps, those communities are spread across a large area rather than clustered into one continuous urban zone. That makes roads, rivers, and valley locations especially useful reference points when learning the county.
Table of Contents
Start with Yreka to make sense of the county’s roads and nearby communities
Yreka appears slightly north of the center of the general county map and works well as the first orientation point. Montague is just to the east, Hornbrook lies farther north, and Fort Jones sits to the southwest. South of Yreka, the main north-south route continues toward Weed and Mount Shasta. Etna and Greenview lie farther west in a separate valley area, while Happy Camp is much farther into the western mountains. Looking at these places together quickly shows that Siskiyou County is made up of several distinct settlement areas rather than one dense center.
The road network reinforces that pattern. I-5 runs through the central part of the county and links the Yreka area with Weed and Mount Shasta before continuing south. CA 3 branches into the Fort Jones and Etna side of the county, while CA 96 crosses the western mountain region toward Happy Camp. CA 89 appears in the southeastern area near McCloud, and shorter numbered routes around Yreka and the eastern side provide additional connections. For a first reading of the map, it is more useful to follow these major routes than to try to absorb every small road at once.
The I-5 corridor ties Yreka to Weed, Mount Shasta, and the southern part of the county
I-5 is the clearest transportation reference on the county map. It enters from the north, passes through the Yreka area, and continues south toward Weed and Mount Shasta. Those three places form an easy sequence for understanding the central part of Siskiyou County. Dunsmuir lies farther south near the county’s lower edge, while McCloud sits to the east of the main freeway corridor. Once these locations are fixed in mind, the western and northeastern parts of the county become easier to place.
Weed is especially useful as a mid-county reference because it sits between Yreka and Mount Shasta and near the point where travel directions begin to spread toward other parts of the county. Mount Shasta is farther south, and Dunsmuir continues the southward sequence. McCloud, by contrast, is not on the same vertical line; it appears to the east and is better understood with CA 89 and the southeastern water map. This simple distinction prevents the county’s southern communities from blending together on a quick glance.
The map is for geographic orientation rather than live navigation. It does not report construction, snow restrictions, closures, collisions, or current travel times. That matters in a county with large mountain areas and long distances between some communities. Use the map to understand where the main routes go, then check current road information before making an actual trip.
The ranked city map separates the Yreka–Mount Shasta corridor from distant Tulelake
The city-distribution map highlights six places: Yreka, Mount Shasta, Weed, Montague, Dunsmuir, and Tulelake. They are numbered from 1 through 6 in the map’s city index. Unlike a connector map, this image does not draw lines between the cities or provide mileage from one city to another. Its purpose is simpler: it shows where the major ranked communities sit within the county outline and makes their geographic spread easy to compare.
Yreka and Montague occupy the north-central area, while Weed, Mount Shasta, and Dunsmuir are grouped farther south. Tulelake stands apart in the northeastern corner. That separation is one of the most useful things on the city map because it makes the county’s width immediately visible. A reader who has only seen the I-5 corridor might otherwise assume that most important communities line up along the same route. Tulelake shows why the eastern side needs to be considered separately.
Neighboring county names appear around the outside of the map as additional orientation aids. The city index also prints population figures, but the map itself is best treated as a location and ranking reference rather than a substitute for current demographic data. Population totals can change and should be checked against a current Census source when the exact year or latest estimate matters.
The Klamath River and western tributaries stand out against the county’s rugged terrain
The terrain-and-water map changes the emphasis from roads and towns to rivers, lakes, and landform. In the west, the Klamath River is the strongest labeled watercourse, bending through a heavily shaded mountain landscape. Mill Creek is also labeled nearby. When this map is compared with the general map, the relationship between the Klamath corridor and the CA 96 side of the county becomes much easier to understand, especially around the broad Happy Camp area.
Farther south and east, the Scott River and North Fork Salmon River appear in separate mountain valleys. The Scott River helps orient the Fort Jones and Etna side of the county, while the North Fork Salmon River sits deeper in the southwestern terrain. Near the center, the Shasta River is labeled as it runs through a different part of the county. These names provide a useful way to divide a very large county into recognizable river and valley areas without relying only on road numbers.
The hillshade also makes the contrast between regions visible. Western Siskiyou County is drawn with tightly packed ridges and valleys, while several central and eastern areas appear broader and smoother. That visual difference can help explain why roads and towns follow certain valleys, but the shaded relief should not be used to measure exact elevations or slopes. It is a general terrain reference, not a survey or engineering product.
Copco Lake, Iron Gate Reservoir, and Tule Lake Sump mark very different parts of northern Siskiyou County
Several named lakes and reservoirs make the northern half of the water map easy to divide. Iron Gate Reservoir and Copco Lake appear near the north-central part of the county. Farther east, Sheepy Lake and Tule Lake Sump sit close to the northeastern edge. Meiss Lake is shown between those areas, giving the broad eastern interior another recognizable reference point. The spacing between these water features is a reminder that the county extends far beyond the I-5 cities.
The northeastern water features are especially useful when paired with the city map. Tulelake, which appears isolated on the ranked-city view, can be related to Tule Lake Sump and Sheepy Lake on the water map. This does not mean the map is showing wetland boundaries, flood zones, or current water levels. It simply provides named water references and terrain so a reader can understand where the northeastern community sits within the larger landscape.
In the southern half, Lake Siskiyou is labeled near the Mount Shasta area, while Lake Shastina lies farther north near the Shasta River side of the county. Medicine Lake is shown well to the east. The McCloud River appears along the southeastern boundary area. Taken together, these features show why one waterbody or one river cannot represent Siskiyou County as a whole; its waters are spread across several widely separated landscapes.
Fort Jones, Etna, and Happy Camp show how far the county extends beyond the freeway corridor
The western half of Siskiyou County can be confusing if the viewer focuses only on I-5. Fort Jones lies southwest of Yreka, with Greenview and Etna continuing down the valley. CA 3 is the key numbered route for this group of communities. On the water map, the Scott River occupies the same general part of the county, so the valley becomes easier to understand when the road and river views are compared side by side.
Happy Camp is farther west and is reached on the map by following CA 96 into the mountain region. The Klamath River is the more useful natural reference in that part of the county. Because the route follows rugged country, straight-line distance on a small county map can be misleading. The map is helpful for direction and regional placement, but actual driving distance should always come from a current road or navigation service.
These western communities also show why a single description such as “north of Mount Shasta” is not enough for Siskiyou County. The county stretches across multiple valleys and mountain blocks. Fort Jones and Etna belong to a different geographic setting from Happy Camp even though all three lie west of the main freeway. Pairing settlement names with CA 3, CA 96, the Scott River, and the Klamath River gives a much clearer picture.
Montague, Hornbrook, and Tulelake help define the county’s northern and northeastern reach
North and east of Yreka, the map becomes more open. Hornbrook appears toward the Oregon border, while Montague sits much closer to Yreka. The eastern road network includes US 97 and other numbered routes that are separate from the central I-5 corridor. Those routes help explain how the northeastern section connects to the rest of the county even though it is visually distant from Yreka, Weed, and Mount Shasta.
Tulelake is the clearest example of that distance. On the ranked-city map it sits by itself near the far northeast corner, and on the water map the Tule Lake Sump and Sheepy Lake area provides a matching geographic reference. This part of the county looks very different from the steep western Klamath country. Viewing both maps together is a simple way to appreciate how much terrain changes across one county.
Choose the map that matches the question you are trying to answer
Use the general county map first when you need towns, major roads, and the county outline. It is the best place to locate Yreka, follow I-5 toward Weed and Mount Shasta, find CA 3 toward Fort Jones and Etna, or trace CA 96 toward Happy Camp. The ranked city map is cleaner when the goal is simply to compare the locations of Yreka, Mount Shasta, Weed, Montague, Dunsmuir, and Tulelake without the distraction of many smaller labels.
Use the terrain-and-water map when rivers, lakes, or mountain context matter more. It is the clearest view for the Klamath, Scott, and Shasta rivers, Copco Lake, Iron Gate Reservoir, Lake Siskiyou, Medicine Lake, Tule Lake Sump, and the McCloud River. A useful method is to locate a town on the general map and then switch to the water map to see the surrounding river or terrain setting. For example, find Happy Camp and CA 96 first, then compare that location with the Klamath River.
These maps are general reference products. They should not be used for parcel boundaries, legal property decisions, live road conditions, wildfire evacuation, flood risk, water quality, navigation, engineering design, or precise elevation measurement. For those tasks, consult the appropriate current agency source. For classroom work, regional orientation, trip planning at a broad scale, presentations, reports, or personal printing, the three maps provide a practical overview of a county that is otherwise difficult to summarize on one page.
Frequently Asked Questions
What is the easiest place to find first on a Siskiyou County map?
Yreka is a useful starting point because the county identifies it as the county seat and the general map places it near several major routes and communities. From Yreka, follow I-5 south toward Weed and Mount Shasta, look west toward Fort Jones and Etna, and look east toward Montague. That sequence provides a quick framework for the rest of the county.
Does the city-distribution map show driving or straight-line distances?
No. This Siskiyou County package uses a ranked city-distribution map rather than a connector-distance map. It shows the relative locations of Yreka, Mount Shasta, Weed, Montague, Dunsmuir, and Tulelake, but it does not draw distance lines or provide mileage between them. Use a current navigation service when actual travel distance is needed.
